Default HELP: Car feels like it slidding in heavy rain

Today is the first time that it's rained heavly here in S. FL since I put my new wheels on, and the drive was scary. I just got on the highway (going about 45mph) and not even 1min into the drive, and the car started feeling like it was slidding all over the place. I stopped, checked the wheels and everything was fine. The entire drive home felt EXTREMELY slipry, and it was scary. Anywhere where there was a lot of water or the road was glossy, and the car felt like it was slidding, almost as if the rear was slidding out from under me even though I was feathering the peddle. I've never been so worried when driving a car in the rain before in my life. Besides that, the car drives flawlessly on dry or semi-wet roads.

Anybody every have this problem? Here are my specs:

- Tanabe DF210 springs
- KYB GR2 shocks
- Axis VIP wheels (20x8.5 +35 & 20x9.5 +40)
- Falken FK 452 tires (235/30/20 & 285/30/20)
- Roughly 6 degrees camber in the rears and I belive 1.5 degrees in the front.

That's a lot of camber in the rear? -1 is factory I think?

Also hows the toe?

How do you have -6 degrees of camber in the rear? Cars on air suspension don't have that much.

Ok, maybe I was wrong. That's what I thought Sears told me, but my memory must be bad.

if you have that much camber, how about some balding on the part thats cambered? THAT would make it slip...

Good question, I've had brand new tires that feel a little unstable, maybe even slippery for the first 400-500 miles. I'm on DF210's and 20" 452's too and have no problems in the rain. Had it just started raining? I've always heard that sometimes the oils and stuff on the road can get a tiny bit slick when it first starts raining, don't know how true it is and I wouldn't think it'd be enough to cause big problems but you never know.

Is VSC off?

At first, just reading the title...I thought for sure its the tires....but they are new...and minimal camber...they should be OK. With those wheel size and offset, you should be flush...without minimal camber needed.

Another reason...but this could be really far fetched is that the tires are installed backwards...meaning its directional...and if installed on the wrong side....the water from the road is channelled to the center of the tire...rather to the side....thus creating a hydroplaning effect.

Maybe the tires haven't been "broken in" yet?

He's on springs. He wouldn't have 6* of camber anyways, like 3-4 max. Check your toe (caster). That's probably out of whack. If not, then it could be the combo of oily road surface and summer/performance tires.

The rear camber is a big issue. Even if you are 2.0 deg. off can cause slip. let's say you are 2.5 deg off, it like you are riding in 1/4 of the patch. That's why only the inner edge wear out faster, it's the only part thats hitting the road.So try to raise the rear camber and check you tires.

My tires are brand new. There's no wear on it yet as I just put them on 3 weeks 2.5 weeks ago.
