Hey I just got a set of powertrix coils and am soon getting 18x9 or 9.5 + 30- 35 rims. Do I need a camber kit? I'm not goin to be slamming it because I daily it but I do want it lowered a bit. I've read that the 8's have quite a bit of adjustment from stock so will I be fine? Thanks

Most of the camber kits you see aren't made for the RX8. Our car uses an unequal a-arm suspension, where as camber kits are made for cars with McPherson strut suspensions. To get more adjustment out of the a-arms you have to get eccentric adjusters that move the arms greater than the oem. They are available from Mazda Motorsports and possibly other sources.

For a street car, what you have (unless they are corroded like mine are and need to be replaced) will be fine. Changing the camber just to put on larger tires? Your doing it wrong.

Ok thanks. Well I'm new to all of this and I told my one buddy( that has a slammed 240) that I just got coil overs and he told me that I'd need a camber kit. I told him from reading on this forum it seems like I wouldn't need anything like you stated too. I just wanna make sure I'm doing it right the first time ya know. So I should be fine then? Thanks again

If you plan to hella slam flush nation your car, the geometry will already be ruined. No sense in worrying about camber.

LCA relative to the driving plane will be at a large angle. Bump traction goes out the window.

thats exactly my goal. no wheel gap with a 18x9.5 +20. Im just really confused to as how you guys go about making the wheels and tires fit. I want to run 265/35/18 but from what J said lowered on konis/tanabe it wont work. So now im looking at 245/40/18

The thing is do i get the tirres mounted on the rim at the shop then tell them to put them on the car, drive around and make changes such as fender rolling bumper tab removal on the spot ??

I personally would put the wheels on myself after the tires have been mounted by a shop.

Rear:
Disconnect sway bar endlink... mount wheel-tire .... use a jack to jack up the wheel .. check for interference. Do not drive around before doing this ... last thing you want to do is realize you needed a roll and blow out your fender on the first good bump

Front:
Same thing, but check clearances with full lock turns as well.

There might be better methods, but this has worked for me in the past.

thanks for the advice. I might get the shop to do all that. Im not very good with suspension work and last thing i want to do is **** up the suspension geometry.

Why not try 18X9.5 +38 or +40..they will fit flush with just a small roll....

Trying to make wheels with the wrong offset fit by increasing the camber is just going to fail on so many levels

getting an INCREDIBLE deal on a set of wheels that why.

And i mean INCREDIBLE

WUZZ DAT ****?

On a more helpful note:

18x10 +40 will fit very flush and stay functional w/a full contact patch, moderate drop and very minimal camber (i have pics for proof if needed). 265/35's fit easy w/nothing more than a fender roll.

18x9.5 w/an offset around +35 should still work. Fender roll and look to fit 265's - 275's no problem w/a 35 series.

They would be more incredible if they fit

Maybe buy them and resell them to buy something that will fit. You likely will spend more in modifications to get them to fit...and aggravation than they good deal is worth

Man seriously I was so stocked on them. Hes giving me an awesome price.

Ive seen people run koni/tanabe with 9.5 +20 and it doesnt seem it was alot of work.

Oggie

there is a rx8 in nz for sale that has 20x10 all round.. I will see if I can find more info for ya..
but it looks like they all fit nicely.

You can make them work...but you have about 3/4 of an inch to deal with on the outside. A combo of slightly narrower tires ( 255 or 245's) with a bit more camber and a serious roll and they will fit.

Just never quite figured out why

FYI..I have 10.5" 18" wheels that fit without rubbing...so it is all about the offset

So from what you saying. If i go 245/40/18 on the 9.5+20 with rolled fenders and slight camber i should be good ?? I dont want too much camber. The most im probably willing to run is -2 maybe. I dont want too much uneven wear on the tires.

Im worried i wont be low enough with the koni/tanabe combo. I need opinions from everyone. Im supposed to pick them up this friday and i told the guy i wouldnt back out :$

Guys thanks for all the info. I just got my powertrix coils in. Now just gotta get wheels. Looking to go with 18x9.5 +35 and bit of a stretch. 225/40/18.

Atilla

iTrader: (1)

^dude, you don't need to stretch the tires to make that fit. That'll easily fit 265/35 with a fender roll. It'll help fill the wheel gap and provide more contact. It'd be stupid to stretch a tire on a sunk fitment...less grip n' still sunk.


It'd be like making out with a fat ugly chick in public........no one wants to see that ****
