Please help asap

Just got 18x9 +38 wheels and was advised 235 front and 245 back. I'm on 1inch lowering springs. Will these fit or they going to poke like a bitch unless I get coil overs camber bolts and control arms?

[churchx]

Not sure who advised that, but on these cars instead of staggered setup i'd prefer square same sized tire setup to not fsck up handling and keep ability to rotate tires.

I think it makes a lot of sense. since you're RWD it'd help with traction and if you do burn outs xD more tire to go. overall it helps performance, but @churchx got a point you won't really be able to rotate but performance or convienent

about the poke the forum has a wheel/offset/camber/lowering adjustment calculator, that's what I use to configure my new wheels. check the offset enough have it just behind the fender line for a good flush look without having it eat rim or fender

Wrong. Square setup is best for this car unless you are building the car for drag strip only. If you cared about performance, you wouldn't get 19 inch wheels.

245/35 or 235/40 or 255/35 are your choices. 245/35 is the best all around for the 18x9 wheels.

khantran04: define performance for you then. After all, even guys going to track or ones developing suspension, advise square setup. And even forced induction/burnouts is not much of reason to put different tires on car ends. If you have forced induction and want more grip, simply put wider but both of same wider width on front and rear. Suspension of our cars was engineered around square setup, electronic nannies like traction control and ABS also expect that and may misbehave or less efficient when it's not. Reasoning that some more upscale cars may have staggered width setup doesn't work, as they simply are engineered to have it that way .. NOT like ours. From practical standpoint it also is good to have staggered wheels & tires setup, as it's easier to find set of same wheels, it's easier to eg. buy 5th wheel for spare if you damage one, without need to buy two or finding available of two different sizes depending if damaged was in front or rear, and as i mentioned above, you can simply rotate front-rear to even out wear and get more mileage from one set of tires. Tire choice for staggered setup often is much more limited, as it may not come in sizes as needed for one of ends. My friend has MR2, that was engineered to have staggered setup. He mostly has only negative comments on that, due all the limitations/extra inconveniences it brings. He'd be more happy to have normal common square setup, if his car wouldn't need staggered one. In general, for this platform most do staggered setup only when they do that for looks reasons (to me it looks more like posing, instead of being cool though), as they try to put very widest ones they can, and it's possible to put wider in one end. Everybody is free to do whatever he wish to his car and money .. but please, don't reason staggered setup with "to improve handling or for more performance". It will not improve, rather will make worse handling/worse performance/less safe/with more issues/more expensive/less practical/limit tire & wheel choice.

Tire compound is far more important the width. I am sure my 225`s will pull more G`s on the skid pad then your 255's, not to mention significantly lighter. just some food for thought.

Churchx is right guys. Seems like you already have the wheels so use one of Swarbs suggestions but get all the same size. The wheel company didn't engineer anything for this car so they probably don't know enough about it to make a sound recommendation. The difference between 235 and 245 is less than your pinky finger anyways. Not exactly a huge gain in performance. For burnouts it won't make the tires last longer either because the tire isn't thicker just wider, it'll be used up just as fast as a skinny tire

You can easily fit 255/35s on 18x9 and they will look perfect with no stretch.

I get what people are saying with the square setup but im running 265 on the back of mine and 245 on the front and have not had a single issue handling wise. Car handled the same with the 265 on the rear as when I had 245s on the read. Maybe im just not pushing the car hard enough?

This is likely. A lot of people will say:oh this will ruin the handling, or that is trash. But unless you are really attuned to how your car feels or you are at the track all the time you won't notice a difference. You get this a lot with heavy(ie cheap) wheels and aero/body kits. Tires it just comes down to convenience for rotating. If you don't drive hard enough to benefit from the staggered setup(assuming you benefited) then why do it to start with?(no pros but several convenience cons)

I guess my main reason for going wider in the rear was better traction for when I end up going FI

Again compound is far more important then width. Now if your going for 400+ WHP then yeah sure you want to run a good compound that is also wide

for sure I get that. I have continental DW so compound is pretty solid tires. Great for all applications above 40degs. Under 40degs you have terrible traction.

haha cant win them all. If my summer tires see -9C they crack and are ruined, if they see rain I am lucky to get to work Because racecar

Also a lot of people think they need max grip tires but forget that at that point you are overloading the stock suspension. You need to increase your spring rate and get damper to match. Its a fine balance between aero (if you have any) Tire grip and spring rates for max performance. Most people probably wont ever reach that point though.

Speaking of springs. Didn't you get 8,9k? What brand were those and why did you choose then over the competition other than the future upgrade?
