Lowering car helps ET? - Honda Prelude Forum

axngen · 02-10-2002, 11:08 AM

I was told on honda-tech.com that lowering your car helps your 1/4 mile time. Does this really hold true? If it does, then I've got more things to look forward to my next visit to the track.. I'll be going w/ new tires (not my 40,000 mile stock ones), a reset ECU (just did it for the first time in 3 years!!), and also my V-AFC.

not to mention some FI hehe if i get it soon enough..

Stiffer springs reduces weight transfer off the front end. That should help your ET.

axngen · 02-10-2002, 04:11 PM

so that helps your launch right?

yes

I wonder what the spring rate are on H&R Sports ? ?

if you tighten the rear shocks and set them on tight, your car rebounds less keeping maximum pressure on the front (driving) wheels thereby allowing u to get a better launch/60ft time helping ur 1/4 time........i've heard u can expect up to 0.1 - 0.3 s gain w/ good suspension set up

H&R sport springs are 25%-30% stiffer than stock... I called H&R and they will not give out the exact spring rates for some reason... the H&R race springs they were willing to give me those spring rates which are 400f/375r

i've got the GC/Koni Yellow setup....so basically all i need 2 do is adjust the two rear shocks to all the way stiff?

i've seen quite a few EBP ludes around here, do you go to UMCP?

C-Redrum · 02-11-2002, 05:42 PM

hmm i might try this the next time i go out street racing...ground control/koni...

I havent even ever adjusted my konis, i just put em on and rode. How much can you adjust them, do they have points or can you adjust them as specific as you want ?

Each shock adjuster has 2 full turns...

after I installed my springs (eibach pro kit), my quarter mile times dropped by .2 seconds.
