But can go drifting now...and tell us how the E90 performs mah. :D
one sentence "Exceeded my expectations" 1. Brakes - sufficient for 5 scorching laps w heavy braking without brake fade. after which feeling gets spongy n softer, partly because tires r also over heated. hard braking at corners is doable n impressive as well, something tt i neva dared to do on other cars. gud combo due to a well tuned car w gud brakes, dsc, suspension, underdrive w gud weight transfer between tires n front/rear so e car feels stable in heavy braking conditions. hard to lock up brakes but gotta be gently w braking, so do abit of trail braking before corners... no point triggering ABS.2. Drive train - Engine Power & Gear & CoolingPower abit lacking n in-sufficient to pull out of uphill slow turns, had to drop to 1st gear at turn 9- 90degree up hill. if u haf gud exit speed on e back strights, a stock STI would take a 325 approximately 5-6 cars by turn 1. if slow exit speed, walaueh easily 10 cars ahead man.. FI FI.. Arnd the track, full throttle on most bends adhering to rite cornering line. and w my setup i never really broke traction until e tires were over heated after 3-4 laps. Had to gun the throttle at some sharper bend + corners but in general, sufficient power to correct minor oversteer. Can play catch up some FI car's arnd e track until hitting e back straights again. No problem with cooling system but i only did averagely 5 laps per session. Gear ratio's r well mated w e engine hp n power band. need to keep RPM at 4k+ n above for N52, RPM climbs pretty acceptable arnd this range. once it drops to btwn 2-4k rpm then u gotta drop gear very quikly so e 320d torque wld fill dis void gap pretty nicely too. the good thing is the paddle shifter reaction time w gearbox is pretty quick so plus point to high revving e n52 once again. e ecu protects e engine from overrevving so all u nd is to downshift aggresively to keep e power going. something tt i learn on track n neva on spiritted town driving. e gearbox takes e power n heat pretty well so it performed pretty flawlessly over the 15 laps tt i took over 3 sessions.3. Handling - Car Settinga. default setting(DTC off, DSC on) - boring, DSC flashing all e time n cuts power to e wheels too soon. b. with DTC on, DSC on - allows more rear wheel slide n spin, increases e FUN factor for most novice drivers. dis is where u get to experience a true FR drive characteristic. minor correction at times wen pushed to its limit but not too restrictive. throwing e back in turn in 2 & 3 n last turn w e rear sliding is so much FUN, e FF cars i was so atuned is so boring in comparison. c. DSC off - slide slide slide, no electronics to help e driver, FUN nonetheless but hazard to others on track. but stil, u need to carry sufficient speed to break traction but once u do u gotta counter steer like yr life depending on it which it does. sideways is e name of the game but 325 definitely not enuff power to power slide unlike e M3 or 335 but sufficient to do DONUTS @ expense of tire wearCar set-upa. stock ARB n bars on Msport is sufficient to gracefully whack arnd SICb. KW's coilover made a big difference in e handling of e car, with my current set-up e rear is less prone to oversteer as before wen i was running bilstein PSS. c. -1.5 rear camber w slight toe in is juz nice for track, anything more will kill e tires in a heart beat d. gud downforce design n perfect weight distribution front and rear. ExperienceMinor understeer at tite corners so they may be a need to push e rear a tad that promotes an oversteer situation.but w e correct suspension n camber set-up dis oversteer situation can be minimized and it took me a while to tune e suspension to get this rite.so in general u get a under under over feeling... better than under under den crash coz yr car is not pointed.. ahaha... The steering response n feedback is gud so driver steering reaction is more immediate and the car behaves in e manner tt is more predictable. turn e steering n u point e car at 1 direction n it goes like a well trained k9, neva out of control bcoz e steering is quite heavy so no major movements tt throws e car out of its balanced rhythm.e msport steering size n grip is e right size mated w sport seats tucked me in pretty well w gud lower back support 4. wear n tear -a. service indicator turun arnd 5k for 1 track sessionb. front brakes down by 8k for 1 track sessionc. rear brakes down by 4k for 1 track sessiond. tires - oouch.... extremely painful n Xe. bushing, etc - yay yay BSRI n warranty while keep'g fingers crossedOverall impression - +ve & -ve1. BMW handling dynamics... WOWZERS2. hard and late BRAKING at corners &/or b4 corners3. KW v3's ze BEST if u ask me 4. PS2 - soft n grippy tires, great traction but tends to overheat n wear pretty quickly due to soft compound5. Abit more power n torque wld be nice but e sound of e 6 pot in full swing it e sweetest sound to my ears.6. ECU too intelligent - Pro's & Cons7. Still understeers a tad but u really need to enter at pretty high cornering speed to experience this, majority of drivers wld not experience dis on daily driven routes.8. lastly turn off DSC n pray hard to God tt u've sufficient skills to drive e carWISH LIST - 30-40 more HP and 60-80nm more Torque, DCT gearbox, michelin sports club tiresOverall Experience = PRICELESS :top:feel free to comment or share your experiences, all for e sake of discussion. always gud to learn from others as well. n don't think for a moment tt i feel that BMW is e best car on track, its NOT but it has impressed me n sufficient to keep me happy for now
 
Wow!! What I meant was go drifting on your worn tires and then tell us whether the E90 can tahan the rigours of drifting. But your write-up is fantastic. Thanks for sharing your experiences and conclusions! :top:
 
If you put this up in 2005, I would have bought an E90 in 2005.. :p :D

Great info though! :top:

Still not too late AB :)

Go get em tiger hehehe...
 
Fantastic review and experience sharing. Should talk to Jeremt Clarkson, who knows, he may invite you to be his guest in his show. Can't wait to go to the track with you one of these days (once i get my e90....hopefully the stock RFT's can take the heat after 4-5 laps. :)
 
I think the club should organized a session as an extension of some of the debate on NA vs turbo diesel etc. and maybe invite a couple of STIs, FDR or Evo for comparison.

My tyres are pretty new, so maybe in the far future ( or get some used tyres!! he!he!he!)

Btw E60Fanster, did you consider adjusting the camber setup just for track, or just use the standard daily. Some guys actually added slight more camber before going to track.

Good info though!
 
e60FANster, your post has attracted many readers. So now go drifting and then post a report! :D

Your tyres are gone anyway, so might as well finish them off and move closer to your service and brake pad interval. Michelin PS2 RFT 255/40/18 fronts are RM1,100 and 245/35/18 rears are RM1,400. Not too bad, and these are the latest prices as I just checked - I'm replacing mine.

in 2005, i still playin vtec n NOS ala Fast & Furious, also how to afford BMW ler.
hope i convinced u enuf to swap yr current 320 for a 325i

tires not exactly all worn out yet, still got 30-40% left in e rear and abt 40-50% for e front.
drifting sure can tahan la but e wear n e bushing on e under links wld be quite bad n tires too.
but if tires gonatz oredi, den drift drift drift...

Did you have the AC on all the time? What was the ambient temperature?

no AC bro, saps e power from e engine, less of it goes to e wheels.
ambient temp is average 30 but on track temp easily 40+ by late am, noonish.
hence tires wld start loosing traction wen over heated due to excessive hard cornering n braking.
slicks w harder compound is required if really wanna track e car, road tires r gud for 4-5 real hard laps.

So Jason, when r u going again hehe?

wen i c my tires n dink abt e cost associated to replacing dem, i'm dinking prob not again.
but wen i dink abt e FUN factor, prob soon :top:
actually i'll prob hit e tracks again soon as e tires wear n when i'm ready to change my tires.
botak tires r less fun n quik but at least can buang abit more to enjoy a truly FR setup.

als tire performance has degraded quite a fair bit after e track day so i'm thinking in e nxt 3 mths or so.
bends tt i normally do at 120, now do at 100 can oredi feel e rear twitchy oredi..
will let u know wen i do, den we get a few fella's n whack whack whack

wow :top:.....which bends do you lift then? T12?

let me try to re-cap the best tt i can.

Turn 1-2 - moderate throttle, throtlle btwn 2-3 gear(based on 325 gear ratio & speed). here is FUN part for FR coz e rear can slide, the FF normally find dis corner e hardest due to severe understeer.
after turn 2, flat out all e way thru turn 3 which is a more a bend then corner keeping e inner right line.
hard braking approaching turn 4, sharp turn in rite, 2nd gear w slight uphill so abit hard to pull but again flat out thru turn 5, off throtle n quik tap on brakes thru turn 6.
den flat out again n b4 turn 7 slight off throttle to cathc rite entry speed if u catch e line den 7 n 8 is one long bend so no point goin in to turn 7 too fast coz u screw up turn 8 by braking.
hard on e brakes approaching hair pin turn 9, here NA cars lose lose lose big time at exit of turn 9.
then once on song turn 10 is off camber turn in to 11, gun throttle till turn 12.
at e start of turn 12 is important, if setup correcly then 13 n 14 is shld be fairly quick exit.
half throttle thru out 12, 13 , 14 actually can gun it max at some point w minor braking.
once after 14 home run till turn 15, juz b4 turn 15 hard braking n slide slide slide... abit lar.
den front straight... RUN FOREST RUN... say bye bye turbo's, R's, GTI's, lution's.. c u again after a few turns.

SIC is hard on e brakes wen coming in to tight hairpin corners but generally mild arnd most part of e tracks.
going off throttle n engine braking is sufficient most of the time but if u drive a monster den u really gotta work the brakes hard.
dat's y sometimes a balanced car w rite hp is gud for a particular track design.
i've tried driving a 400+ ATW evo7 on SIC, i gave up after 2 laps.
coz
1. i'm a lousy driver n power was crazy
2. too much boost n timing of e boost, especially wen it comes to e corners like on/off feeling wen gunning throttle
3. too much hp for the tires n suspension/chassis to handle
4. messing up w the gears selection and its ratio.
5. too much hard braking, normal coz carry too much speed b4 hitting e turns

yeah get invited as STIG, i dink i cant fit e suit lar.
BBB.. beli first den worry later, i'll b glad to show u arnd SIC in yr new car.
stock rft's shld b able to take 4-5 laps.. TOPS if u drive it hard arnd noon.
if early am's den probably can last 2-3 more laps.... brakes cld pose n issue too

dat's y endurance race is a different strategy all together, conserve brakes n tires w consistent lap times lap after lap

bro, e debate will neva end as long as ppl haf individual preferences. no matter what e outcome is. dat's y many mature forumers say to "to each, his own".
was contemplating -2 but i also wan to conserve my tires lar, michelin not sponsoring me ler.
on street i run -1.3 on e rear n close to -1 at e front but rear wear is pretty un-even, cant help it.
but e front wear is somewhat even so to speak and i do whack corners frequently when e road r clears of traffic, i'm a responsible citizen :top:

WOW those r gud prices, i remember last year it was arnd 7k for a set, now 5k only.
i'm on 235/35/19 F n 275/30/19 R & non RFT's so it shld cost me arnd 5.4k to swap a new set.
but i'm broke lar, juz renewed my r/tax n insurance but still got thread so hopefully got bonus come CNY.
hope my tires can last till den so "conservation" is e name of e game
 
Shucks...:hmpf:

But can understand of course. The E90 is not exactly a car you want to use for track and such, unless you have loads of dough or are a kept man! Not like climbing into a track/rally ready car like an EVO or STI. No guilt about whacking then eh?

Not bad hor, for what is essentially a cruiser with some sports DNA? And totally stock too, with road wheels! Thanks...for this entertaining thread. :top:
