[QUOTE="morrogan, post: 565022, member: 19033"] Bro Wobbles, Sorry for hijacking your thread. Just did a study on entrance and exit angle + ground clearance on your forecoming F13. From scaled traced image, your F13 should have a ground clearance of ~150mm (unladen). Based on that, with the stated front and rear overhang, the entrance and exit angle is approximately 15 degrees. And logically, you will be fine crossing over speed hump not more than 130mm in height (the 20mm reduction is due to your weight+passanger weight+some light booth load+slight re-bounce from the absorber). If all speed hump is constructed in strict accordance to LTA's standard then you are fine to go ahead with the lowering (see enclosed LTA's standard speed hump which indicating max height of 100mm). However, as far as I know, many private speed humps do not follow the standard and especially in Malaysia, you have got hundreds of do-as-you-wish speed humps w/o following the recommended design. It is already dangerous when we opted for the nice looking M-Sport bumper as it had protruded lip+ built in aerodynamic splitter. If lower somemore, risk of hitting is really high.
