Wheel spacers

[tIANcI]

Zul ... How much were the HREs :0) ... I did see some 17" Japanese magnesium rims before, they were light enough to pass around like a basketball.

Well, can't go for 20mm as I already hit the limit. Running ET15 at the rear with 10mm spacer and ET30 with 5mm spacer at the front (front can go another 2-3mm).

Of course if you whack 50mm spacer the car's handling will be altered. The key is to get to the sweet spot, just like eating fruits...too much you Lao Sai

 

[Zul]

bro after u try 20mm each sides do let me know how is the handling...hehe

Wow, 20 mm spacer... I think that is too much unless U modify your fender...

I'm using 15 mm for my front and 10 mm for rear. On the previous M3 I've used 15 mm front and 12 mm rear. Be careful when U used thicker spacer because basically it reduce the ofset of your setup. If too much your tyre will rub your fender. The 15 and 12 mm is the max for e92 M3 with style 220 and the 15 and 10 mm is the max for style 359.

For non-M I'm not so sure, have to measure.

If U plan to lower your car then put the spacer only after U lowered the car.

Spacer adv vs disadv have a lot of discussion if U search fpr it in the web. A lot of people used it and tell u there is no problem and al lot of people will tell U that it will cause early wear and tear. In the end U'll get confused and have to make your own choice.

As ALBundy mentioned, the track become wider in the evolution of the car.

IMO it gives more stability on cornering. Just make sure U use a good quality, hub centric with corresponding longer nuts. Most 'branded' wheel spacer with come with the correct length nuts.

Be prepared to sell one of your kidneys for a 3 piece HRE

The HRE C20 3-piece forged I bought last time at RM 18k. Not sure of the 1-piece P40. Must be cheaper than that. I got it from Singapore delivered to my house.

One of the bench mark I used is turn 5 in Sepang. The e90 that we used for driver training never ceased to amaze me with the speed it can take the corner, and my ///M with stock suspension settings isn't any faster. Of course after some stiffer ARB and wider track width via spacers, it makes a big difference

 

[t2ribena]

my point earlier is adding spacer excessively is not going to improve handling as all cars has their own steering and suspension geometry...by just adding spacer it is misleading to say that it improves handling...then ppl just go and get the thickess spacer that they can fit in front or rear limited by their cars fender limitation...this might if u lucky improves the handling or if unlucky makes it worse...

new cars that comes out gets wider track...yes but the car maker do take into account alot of factors like scrub radius, front vs rear track offset and etc...

so since we are not so deep into calculating the actual spacer we need to correct the inherent understeering built into the car by the maker, we can just do it by try and error...but by saying more spacer thickness is good is misleading and not true...

Turn 5... the fast left turn/corner...... Can feel the G-force...

Totally agreed with U. Don't overdo it, as ALBundy said, U have to find the sweet-spot of it...

 

[tIANcI]

Zul ... 18k ... Hmmmm ... If sell my kidney can get about 30k then got 12k+ balance to get new M performance steering wheel la. :0)

Ribena ... Just add to the max and then cruise around to show off. No need to worry about geometry and handling issues.

Bro, don't sell so cheap. In Singapore U can get $50k lah...

TQ TQ! Now can buy some titanium pipes too!

I think what is a good example is the e46 m3 csl. The csl has got wider rims, 8.5j versus 8j(stock) and it basically makes the car more neutral with more front end bite. Again, it's about finding the right balance. There are not that many spacers we can play before the tires start rubbing against the fender. 5,7 or max 10mm, for the e46 m3. Bantai maximum in Sepang and you should know what is the best setup That's why even formula 1 teams need plenty of test time to get their cars properly setup despite having the best engineers doing all the calculation

 

[supergripen]

Agreed..its all about balance and finding the optimum or sweet spot I guess.And of course for most of us mere mortals the only way to go is to learn from experiences of others and also by trial and error.
Honestly,all I want is for the car to look nicer and more aggressive without having to go with 19" alloys.If by doing so improves the handling of the car,all the better.Won't be racing the car so that hundredth of a second per lap won't really be that important,as long as it doesn't destroy the inherent handling balance of the car.

I added a set of 15mm spacers to the car today. It does look nicer. The stance is wider and the first thing that comes to mind is that its garang like an EVO X! The E90 is so much chunkier now. With the original set up, the gap at the wheel arches were not obvious, now with the tyres further its more noticeable. Did not get to drive it much as traffic was slightly heavy but it felt as if there is less understeer now. A slight bit lesser. Hmmmm ... need to tekan a bit and see. Guess, this will be a temporary mod until I can find a nice set of offset rims.

 

[ALBundy]

Go for a set of forged 19s!!

Al ... I would like to but to spend 9K on a set that is not much lighter than my 193s I feel its not worth it, let's not forget a whole set of run flats, about another 6K. Then the nice nice rims are usually about 15K (plus another 6K), me thinking either RM15K scrape the kerbs or see my car on bricks. Surely I cry either way. LOL! Lemme mull over it ... its either a nice nice set of rims or a HKS SC for the CRZ.

That looks pretty good bro... nicely squat and wide.A tad bit lower on the ride height and it'll be perfect.

Not really feeling those front splitters tho.. but hey,to each his/her own right?

Nice ride I'm not sure if the rear would rub, you probably need to take a few passengers around our wonderful wavy Malaysia roads to tell.

aoch88 ... will not la ... springs are not lowered. Hehehehehee ...
