Race Alignment specs???
Race Alignment specs???
Hi,
I've finally bought a set of coilovers and I need to know what specs to go with for an alignment. My car is not a daily driver nor am I concerned about tire longevity. I do HPDE exclusively.
setup
Ohlins Road & Track coilovers
Whiteline Front and Rear swaybars w/ upgraded endlinks
Whiteline Front Roll Center adjustment kit
Hankook 255/40R17
Stock Rear diff.

When I have the older Ohlins R&T, I ran -2.8 in front, -1.8 in rear, and zero toe all around. From my little experience in autox and hpde, the Evo likes front camber.
i just did one event on ohlins r/t, whiteline sways front and rear (rear on middle hole) and the following:
-2.8 front camber
0 toe
-1.5 rear camber
1/16 total toe in
car was very composed and trended towards understeer in a "safe" way. ran 8 clicks back from full stiff on the front and 10 clicks stiff on the rear. definitely could have stiffened the rear some, but even still, the increase in lateral was quite amazing.

I run almost the same setup. R&T, roll center kit, just installed the whiteline ALK for an additional half degree of caster, and 255 rubber.
I align at 2.8-3 front camber
1.8 rear camber and 0 toe all the way around.
I am still on stock sways but run 700lb springs in the rear and 575 front (12k / 10k)
Hope that helps.

yes it was pushy, i kind of did that on purpose, because i am still a somewhat novice driver, so id prefer to have understeer to dial out as opposed to oversteer.
i had planned to stiffen up the rear rebound, but the day did not go smoothly and it kinda slipped my mind. i also added the tad of rear toe in in preparation for some splitter testing in june.
what do you think the best approach to "loosening" it up gradually is? i had tried to start a thread about setting rebound, but got very little response.
I guess to me comments like 'novice driver' and 'splitter testing' make me scratch my head. I don't think rebound is the first place to find rotation...
Basic alignment changes are the first thing on the low-cost 'testing' list.

i call my self a novice because i dont think im billy badass know it all (i run in the "intermediate" group with all organizations i run with, running my first NASA event next month finally, so I will report back what they tell me). it will be 10 years before i consider myself advanced. i pride myself on being safe and knowing every inch of my car, how it behaves and how to control it.

Toe-in is used for straight line stability. Toe-out, especially in the front, will aid during turn-in.
BTW, here are my settings for autox.
-3.5* front camber, 1/8 total toe-out
-2.2* rear camber, 0 toe
Weir Performance Max Grip LSD kit--***Must have, fraction of the cost of purchasing an entire unit.

ok, so what in my alignment settings makes you say push? lack of front camber? i think the tiny amount of rear toe is almost negligible honestly. the rebound comment wasnt to necessarily find rotation, but to lessen under steer to a degree...i thought.

yeah i know. its a theory and application thing for me at this point since i have just switched over to coilovers and have more adjust ability range. i guess the story is that most of the faster guys are running -3 or more and toe out in the front?
