Default Suspension "What Do i do now?"

I bought my rims +tires yesterday 245/35 R19+ 295/35 R19 toyo tires , and i had just mounted them when i noticed that they slightly rub ( it is 2007 enthusiast stock suspension) when i take a corner fast. I am thinking about gentting a kit of Eibach Sportline springs+ sway bars (eibach too) , would that work , will it rub again , also what a friend of mine scared me is the alignment of the rear tires, so do i have to do something about it or just spring and sway bars work well , plss need advice thnks

if you lower the car, the camber will be more aggressive (more negative) but will still be the same as when you 'corner fast'.

Get the springs/bars, but also find some rear camber arms. SPC makes some for ~190 that will solve the issue completely.

What rims are you running? Offset?

295/35/19 is the wrong tire size. You want a 295/30/19. Find the idiot that sold you those and return them. The tire combo you chose is really bad. If your going ot run a 295/30/19 in the rear you want to run a 275/30/19 up front. 50mm of stagger is way off.

Because some of us don't like to under-tire the wheel. Even 275 is a little bit too small for a 10.5" in my opinion. And a 10.5" lip looks better then a 9.5" lip so i guess looks and traction.

People like what they like.

Now onto answering your question.

Can you tell us your offset?

Your most likely going to have to roll the fenders, especially if your rubbing and on stock ride height. If you lower your car then it's going to rub more unless you roll or get a camber kit and do a crazy - camber setting...which i wouldn't recommend for driving around.

Ok let's put it this way. If I purchased a set of 9.5 and 10.5 lets make it a 18" what tire sizes would you like to put on it?

Stock 18" wheels/tires were 53lbs/57lbs, 19" Volks and Michelin PS2s are 44lbs/48lbs.

255/40 up front, 275/40 on the rears would have the same OD as the OEM tires. That would keep VDC/TCS happy, correct speedo/odometer readings.

You are correct in your previous statement about 275's being a little too small for 10½" wheels. I would really go with 285s but 40 profile make the rear a little too tall and 35 would be a little too short.

You also need to check on the availability of tires in these widths and 18" diameters. They might be hard to come by. These width wheels and tires are more common in the 19" wheels.

That would be bad. Especially in Advent7's case since he has a Touring with VDC. The fronts would be 0.4" taller than the rears and that would cause problems with VDC.

JUN has 18x10's on all 4 corners with 265/35/18's on them with 800hp. Why did they do this if it's not a good idea?

If "what's" not a good idea? 18x10? 265/35/18? Non-staggered setup?

I was referring to the "puny" 265's. Earlier it was stated that wider is better and undersizing is bad. 275 on a 10.5 I believe was said nearly undersized. A 265 on a 10 inch wide wheel would probably be considered undersized or nearly undersized I think.

Also that they have a relatively small 265 width tire and 800hp. The thinking on this forum seems to say that 265 is way too small for 800hp, even with AWD.

umm, ok thought we were discussing tire width and added weight from a 265 to a 295 tire not from 18" to 19".

but anyways, your 19" may be lighter, but you are also placing all the weight further from the center of the hub. so it will require more rotational force to move a larger rim.

dont knock it till you try it. had 265/35s and 235/40s on my car at the tack and i have a touring w/vdc as well but whatever, just my .02

also, he said what tires would I like to put on it. he doesnt have to listen to me now does he.

Agreed, that much HP should justify more rubber. I run those sizes on my autocross setup.

Yes we are talking about wider tires. In your previous post you brought up the issue of increased weight. I pointed out that it is entirely possible to go with wider tires and actually reduce weight.

I've done the calculations and the rotational inertia increase by going from 18" to 19" is essentially offset by the reduction in weight from that setup.
