What after market wheels for cup racer geo/suspension

[av4625]

Anyone found reasonably priced after market wheels that fit with the cup racer setup?

Most after market stuff seems to have a lower offset, with the cup racer widening the front the lower offset would have the wheel in the arch I think?

Define 'fit' - depends on how much you like your outer arches and how far you're willing to go with other modifications to make more room.

Define 'reasonably priced' - depends on how much you want to spend, whether new or used, and what weight.

Have a read of my progress thread for an idea.

I know you should not believe everything you read on the internet, but, I thought that Cup Racers with their special front end had a wider track, and also had spacers on, together with 8J wheels. Is that correct?

Also, were the Cup racer cars bastardised to make the wider fit work just by cutting away the arches or making adjustments that we don't have on road spec cars?

 

[R20BTG]

Yes cup racers have wider track due to the EE brackets pushing everything outwards. See thread here for the explanation.

Cup Racer EE Brackets & Roll Centre Correction - The Numbers...

One thing that I’ve heard mentioned on this forum is the lack of ‘numbers’ surrounding the performance difference between OEM front end setup and the ‘cup racer’ front end setup. The 'cup racer' setup consists of correcting roll centre and bump steer characteristics by: - Raising the front...

They ran the 17x8J Speedline wheels (ET68). Most genuine cup racers I've seen have their outer arches, arch liners and the back of the front bumper rubbed away, so they certainly didn't have perfect fitment from the factory.

Not sure if they ran spacers, I doubt it.

Thank Iain.

Have you got a set of 7.5J wheels - if so do they fit better?

 

[R20BTG]

No I run:

- OZ Ultraleggera 17x8J ET55
- Braid Fullrace A 17x8J ET50

No spacers

So the Cup Racer Speedlines (ET68) will sit 13mm and 18mm further into the arch respectively.

In all these shots of X85 Cup Cars you can see the rear of the front bumper has been rubbed away, presumably because of the increased caster, albeit the top of the wheel is tucked into the arch more because of the higher offset Speedline wheels compared to mine:

Thats right. They have wider track by a little over 20mm or so. I believe they also ran a 5mm spacer and they did have the 8J wheel.

The speedline is ET68, but most aftermarket wheels you see for clios are around ET50-ET55 which would push the wheel out even further along with the wider track.

On my car I have the cup racer front end, I run 200 cup wheels atm which are 7.5J and I think still ET68 or similar to that at least. I too run the 5mm spacer.

This setup fits quite nicely and the 200 cup wheel is a good bit lighter than any other stock wheels. I don’t get very much rubbing at all. If I hit a curb hard the front bumper pops out between the bumper and wing. I haven’t strapped it in as I feel its more likely to break then. I’d rather just push it back in after a run.

I’d like 8j wheels with a similar offset to oem as thats what the cupracers were designed to work with, and so far it seems my only options are speedlines. But they are very heavy. Braid can do any offset on the forged 1 wheels. But silly money.

I think all 197/200 bumpers are prone to popping out when they hit a kerb or bump hard enough.

The pics of the cup racers seem to have a bolt or something there. Probably why they rub more than mine as it pops out slightly lol

I’m sure I read somewhere that that the cup racers ran 5mm spaces on the front

Same. Thats why I run them on mine

Yeah 5mm required if using the 8J as the EE bracket fouls on the rim, fairly sure it’s a fix rather than enhancement.

Well every day is a school day

Good info! Didn't realise it was a fix, I just thought they chose to run it. Might try without on the 7.5J wheels

 

[LiamP]

I can’t find where I read this now so don’t hold me to it, however I remember it being very tight with standard 7.5J.
