Geometry Set Up

 

What?! lol

 

Theoretically speaking, how low and how cambered would one need to be to fit 18x8.5 0 offset with 245 40s? Obviously rolled fenders and shaved tabs to start, but think theoretical, i am not planning to do this just curious.

 

I like the using the word rhombus. It sounds fun.

No, you shouldn't need an alignment. Your camber and toe stay the same but further out to the corners. Start lowering things and then you need an alignment because those geometries be changin' yo.

 

I guess it would put you just a few mm out past where I am without the slight tire stretch. I rolled my fenders a bit and still have some room so I'm guessing it would work out okay. Maybe a little of the cambers.

 

What are you lowered on? s-tech?

 

Yep on the stech daddies. I am on 18x9.75 +20. I rolled and trimmed as a precaution and maybe a bit because I was bored. 245/40s. I almost feel like I could go to a 255 or 265/35. We will see when I get the coilover moneys together.

 

but why...

 

Why not? like I said, purely theoretical.

 

Yeah, it is possible with modification......don't think anyone here, including me, would recommend that.

Why would you want to run 8" wide wheels with a 0 offset? Have some used Cragars off another car?

 

It just doesn't make sense.

 

i need a opinion on this sizes: 245 35 19 front 255 35 19 rear -- 245 30 19 f 265 30 19 rear orr 265 30 rear im sitting on teins but im going to replace it for coilovers soon
wheels size 19x8.5 +23 front 19x9.5 +28 rear.. thanks

 

Fronts are easy but rear will need 265s to look good. I have the same fitment in 18s and had to trim my rear bumper tab + roll fenders. I'm much lower than tein springs though. It will probably look like crap until you go lowwwww

245/35f 265/30r is my suggestion. 265/35/19 should work too

 

i agree i have to be low to get a good look im planning to buy and install the coilovers when my car get out of the body shop..
thanks for the advice

 

18x10 +4 Front and 18x11.5 +4 Rear

Will it fit?

 

Hi guys ive been reading through the posts and my head is hurting from all the information.............lol

So here goes,i have recently bought a 40th Anniversary RX8 in Crystal White Pearl...............

I have ordered Tein S springs and im now looking at fitting these wheels,so any help would be greatly appreciated......was thinking same size rims all round and 225/45/18 front and 245/40/18 rear or 255/35/18s?

Rim Size: 18" PCD: 5 x 114.3

Size Width: 9.5"

Offset: 35mm Ultralite Hikari in gold with stainless lip....

I dont want to start rolling arches if at all possible.....

Many thanks guys from a cold and wet day in Ireland

you're fine with 245 or 255, no roll needed.

 

What he said. 255s all around.

 

yep.....don't put 225/45/18 on your 9.5" wide wheels. 245 or 255 will be much better, even on the front.

 

ok guys thanks for the replys....anyone any pics of the above wheel sizes fitted?

Regards

Seamus

 

275/35 all around

 

I know this is a stupid question, but what is the most (width) tire size that you could put on a oem rx8 wheels? No spacers, just lowered sunk...without hitting the fender...

 

I think I've seen some of the autocross guys fit 285s or 295s on stock wheels but I'm not sure if they are doing fender work.

 

That's crazy excessive for the stock wheel. I wouldn't recommend anything over 255, and even that's pushing it I believe.
