Do you have a picture?

To change that into "it was great!" instead of "wasn't so bad", raise your car. No lower than 4.75" from the pinch welds.

Yes, I have. The only problem I have that is listed is the drop of coilover.

Hard to tell. Car looks nice but I would probably raise the rear slightly and maybe the front. KW V3 are good coilovers when set up well and a great coilover for someone that's new to the track. But you gotta have them set up well.

Either way, you need more front camber...max it out at the lower mount since you don't have plates and you'll be in good shape (though a little more would be better). Reduce rear camber when you get your LCAs to around -2.2 or so.

Thanks! Was planning to lower front to -2 and rear to -2.5 but I'll go with -2.2 rear now

You'll want more than -2 front if you can get it.

As much as you can get honestly. Without plates with V3s you can still get a decent amount....maybe -2.5 or so (off the top of my head).

If you can't get much neg camber in the front I would start looking at camber plates. -3.5 since your car is not a daily.

And yes raise your car. You want to regain suspension/shock travel.

Yes, you should think about getting some camber plates.

Generally speaking, you want to start at -3 in the front, and adjust accordingly for the front, based on your own needs

Rear will usually fall between -2 and -2.5

So, I have an issue with my car. When taking high speed corners (60 mph+), I'll have my steering wheel set at a certain angle and I'll be controlling the angle with the throttle.

However, despite holding the wheel at the same angle, the car will suddenly veer violently into the turn (for example, if I'm taking a right turn, it'll suddenly veer violently right). This is really scary and I'm not sure why the car does this. It usually happens when there are downward elevation changes or dips.

I have stock suspension, stock tires, and a DriveWay Labs diffuser. I have hit a curb and set my alignment off a while ago, though I had it realigned at Toyota back to stock specs.

Stability control on or off?
What kind of tires?

If VSC on, it's probably fixing a driving error (preventing a spin). If VSC is off, thats you losing/gaining traction over the dip, possibly from inner wheel spin, sudden traction loss, not enough droop, or running out of bump travel..

Fix it with either an LSD, better suspension, or both.

^ is what you said in a previous post on a different thread. I'm just wondering what is your real input on the rad. You put a larger rad on your top 10 mods. Thanks!
