Im after getting 2 new Pro Race 1.2s for the rear of the 3dr to fill the arches better.

Im thinking of getting 17x8 ET25 with 215/40 tyres

Is the above size the best to go for ?

Also what is the best place to get the wheels from (cheapest lol )

Steve

 

Iv got et25 comps on a 215/40 and i reckon i coupd space them out another 10mm which i will be doing tomrrow so will be down to et15

 

The wheels I have at the moment are 17x7 ET35 with 215/40 tyres.

I didn't want the ET to low as I don't want tyre arch contact and I don't want to cut the arches.

Steve

 

My rear offset on my 3 Door on a 8 x 17 rim is ET17 but I reckon you could go even less.

Best set up for a 3 door is 8j ET30 on the rear with decent shocks they won't catch the arches, take a look at the first pic on my 3 door for sale thread.

 

I have 8x18 ET35 front and ET25 rear with 215/35 front tyres and 225/35 on the rear, I reckon that's the best compromise if you actually want to be able to carry passengers in the rear. Trouble is with 17" wheels no one seems to make a 225/40 rear tyre which would be ideal on the rear with a 25 offset and maybe a 215/40 front.

 

I would say et30 on a 8x17" wheel and 215/40/17 tyres with no arch mods,anything below and I think your gonna struggle with arch contact from the tyre.All this presuminmg you have Konis and a decent set of springs fitted to the car,from memory you do so that's what i would say from my experience from owning 4 3dr cossies (inc a 500) ranging from 17" to an 18" wheel.
I hope this helps Steve.

My old MO6 were 8x17 ET25 rear - my arches are trimmed and rolled for 8.5x17 ET22

Steve you really want 235 rear mate

 

I tried fitting 235s on the rear and they rubbed my arch even when cut right back prob due to me swapping my coilovers for konis

 

Which side of the world are you on now mate? What's in your car collection now? The 8k mile moonstone? The red esc? Kev Sharp's old black 3 dr? Dad's 500? I'd love to know how they all are

 

Hey pal, im in melb at the mo hows u?

Erm-

Black 3dr (kevs shell)
Black Rs500 (old mans)
8k moonstone 3dr
217mile escos
White 3dr rs500 engined
Ultimate green Mk2 RS
Had a Frozen White 530hp Mk2 i sold a couple weeks back
Just bought a 3dr thunder saloon

 

And put a deposit on a M135i for daily duties

 

Would a 10" rear wheel fit ??

 

Bearing in mind Steve doesn't want to cut the arches as he has already stated.
Put it this way a 235 tyre with an et25 rim, would defiantley foul the arches,I know Justin had this set up on his white 3dr and had problems with the tyre fouling the rear arch,his car was fitted with fairly new Koni and Ahmed springs at the time.

I had a 235 tyres on my last 3dr with the cxns and they were an et35 offset,arches were trimmed but the tyre did contact the front end of the rear arch occassionally.
I think if you had coilovers fitted you are open to more options as there is so much more adjustment with ride height etc than on the Konis.

Why not just try a 6mm spacer on the wheels you already have just to see what it looks like or be brave and try a 10mm spacer, just to see how it looks and if you get any fouling issues once driving the car. You won't get any problem until the car squats when it comes on boost then that will tell the true story.Stick with the 215 tyre as the arches are uncut and you have the Konis already fitted up. It's a minefield Steve,trial and error I'm affraid.

Awesome mate. I'll send you a PM so as not to clutter this

 

It would be a lot cheaper just to try spacers first as you say. Do you need longer wheel studs with a 10mm spacer ?

The car don't boost hard enough to squat

Steve

 

I run 9x17 et23 pro race 1.2 you are more than welcome to try my wheels on the car I have 16 of them lol

 

Well I have got longer 63mm wheel studs fitted on my car,should be fine on the standard studs though Steve,at least just to try out a set of spacers anyway.You could go for 47mm wheel studs if you think there's not enough turns on the standard studs.
As for the car squatting, well yes I know it's a stage 1 chip,didn't like to mention it won't boost hard enough for the car to squat properly which maybe a good thing as far as your wheel offsets go.Try some spacers first just experiment a bit with them as I say 6mm,then try a 10mm if you feel the 6mm aren't sufficient and as long as they don't foul the arches of course.

Thanks.Lee.
