Ok so I went to the Streets of Willow at Willow Springs raceway and as normal for a FWD car, I was getting a lot of understeer initially. I fixed most of it by softening up the front dampers, and After that, the car felt pretty stable all around. I wasnt getting oversteer, and I didnt really have any understeer issues unless I was clearly going off the driving line and trying to correct it. However, I do have some stiffer rear springs just sittin here.

So what I would like to know, is what would be the result of me throwing in stiffer springs? I would be running the same alignment, same everything. The only difference would be the rear spring rate..

My current rear springs are 10k.. The new ones waiting to be installed are 14k

----------------------------

Here is my current track settup:

Engine:
apex N1 catback
T1r test pipe
custom ram air intake w/ K&N air filter

Suspension/wheels/brakes:
skunk2 Pro-c's 12k front , 10k rear
dampers set to full stiff in the rear, 5 clicks from stiffest in the front
progress 22mm rear sway bar
alignment (camber) = -2.5 front ... -2.3 rear
Volk TE37's 17x7.5
Nitto NT01 225/45 R17
air pressures = 35 front, 30 rear (all cold)
porterfield R4 front pads, R4s rear pads
stainless lines
ATE super blue racing fluid

I gutted the interior, no rear seats, no front passenger seat, no interior trim panels from the b-pillars and back, no spare tire or trunk liner.

I also have an APR front wind splitter
