Track wheels - Cayman 987.2 S - Page 2 - Boxster/Cayman - PistonHeads UK

Revolution CR10 might be an option, although i think they are 18”. I’ve got a set of 19” carrera sport alloys (the same width and offset as the spyder/R wheels, slightly wider track than all other 19” options) with sport contact 7 tyres that are available from my old 987.2 They do fit my 996 but I’m looking to go back to oe sizes.

Thanks both for the responses Philvrs, My standard 19" alloys are 8.5 and 10, are the option you are talking about 10.5 or 11 at the rear? To be honest I'm not looking at increasing tyre width much but would accept a smidge wider. ATM, Michelin don't list cup2's in sizes below 19" on their website, 18" would get great as I'd get compo's on there There would need to be a good tyre available though and be fiarly future proof with diameter's constantly increasing. Cheers, Dunc.

I thought it was only the spyder/R and the wheels pictured that were 10” rear, others are 9.5”. One more quick question, are you competing (time trials etc) or just enjoying track days? If the latter i would get the 18” wheels i wanted and use a cheaper non cup2 tyre, i would still get the same enjoyment that way. Otherwise, its extra transport and a set of slicks, if being the fastest is the only way to get your kicks.

Thanks ATM, I wasn't familiar with that brand so not too sure of quality but they look nice Philvrs said: Which 19” wheel design do you have?

Sorry they are the same as yours, Carrera sport: https://teile.com/en/porsche-tequipment-shop/model... Ex racer but back on track days for now, I find standard style tyres like PS4S overheat very quickly and are ultimately unsatisfying. I like slicks but I'd be looking to drive to the track and maybe sunny road runs too. Cheers, Dunc. Edited by dunc_sx on Sunday 17th March 01:43

https://revolutionwheels.com/uncategorised/cr10-wh... The CR10 is available in 19” in a variety of widths, maybe an option for a lighter weight wheel similar to OZ (but UK made)

dunc_sx said: Thanks ATM, I wasn't familiar with that brand so not too sure of quality but they look nice You misunderstood the point. The point was you don't need to be married to standard tyre sizes. If you look at the link they recommend several different 18 inch options. I'd say 245 40 and 275 40 18 is the one I would go for.

Certainly plenty of dedicated track day and race cars running 18s instead of 19s on .2 Caymans

Needing to drive to the circuit and have a specific tyre requirement that is only available in 19” or bigger means a very limited choice of wheels for the OP.

I just checked. The Michelin website have no cup 2 listed below 19 inch. That's surprised me. I thought they were available in 18 and even 17. I'm pretty sure they used to be so maybe something has changed.

Ok sanity has returned. Asda tyres list a couple of 17 and 18 options for cup 2. So I wasn't going completely mad. But that doesn't help the OP. The only options for 18 are 986 sizes 225 40 and 265 35. There is also 235 40 and 245 35. So if you are willing to go down to 265 35 18 rears you could use any of the others above for fronts. https://www.asdatyres.co.uk/michelin/pilot-sport-c...

freedman said: Certainly plenty of dedicated track day and race cars running 18s instead of 19s on .2 Caymans I'd be interested in which tyres they use if you know, more so the track day cars? ATM, So Pilot Sport Cup 2 Connect comes in 17" to 21" so happy days there.

Just updating this, I ended up going for 18" Revolution CR10's in the end. They were 8.5F and 10R, front were a standard offset and the rear offset specific to my request. Price was £1.3k inc VAT and delivery, lead time is 4 to 5 weeks so plenty of time to pick up a set of tyres. Cheers, Dunc.

What tyres you gonna go for?

ATM said: What tyres you gonna go for? Hi ATM, Sorry for the slow response, just came back on to provide an update on the rims and saw your post. I'm going for AD09. The revolution's arrived this week so I stuck them on the scales in case anyone is interested. Front 18 x 8.5 ET45 = 9.5 Kg Rear 18 x 10 ET32 = 11.2 KG Now to get tyres on and see how they go Cheers, Dunc.

dunc_sx said: I'm going for AD09. Standard sizes? 235 40 265 40

ATM said: Standard sizes? 235 40 265 40 Yeah that's what I thought, until at least I judge how much space there is for wider. However only 245 40 / 275 40 AD09 seem to be available on any UK track tyre site I can find. This would be fine however I've read the tread on AD09 is particularly wide compared to other tyres so I'm a bit worried about clearance at the front. According to manufacturers spec for example the AD09 is listed as having a 18mm wider tread than the same 245 40 Cup 2, which is pretty crazy. Actually the 225 AD09 has the same tread width as 245 cup 2, unfortunately 225 AD09 isn't available in UK either. As with most things the selection process won't be quite as straight forward as planned, I'll get there though. Cheers, Dunc.

Updating this in case anyone is searching for such information, I've added it to the original post as well. Revolution alloys CR10 Front 18 x 8.5 ET45 = 9.5 Kg Rear 18 x 10 ET32 = 11.2 KG MRF ZTR trackday tyres Front 235/40R18 = 11.5Kg Rear 265/35R18 = 12.2Kg Total track day wheels Front = 21.0kg Rear = 23.4Kg For referance my standard set-up as it left the factory is: Rear = 25.0kg (19 x 8.5 235/35/19) Front = 21.2Kg (19 x 10 265/35/19) Total saving 3.6Kg with a swap from 19" to 18" with similar tyres sizes. Dunc.

I'm starting to look for a set of track wheels for my lightly modified 987.2 Cayman S. 19" to put Michelin Cup 2's on because I don't fancy the cup 2's for daily duties. There seems to be limited options for straight fit sizes unless I'm doing a poor job of looking? Options I have seen: Std Porsche wheels OZ Leggera HLT Apex (China I think?) Am I missing any obvious choices? On race cars I've previously used Compomotive and Image, both of which were ok. Cheers, Dunc. Edit: adding my final selection inc. weights for anyone interested: Revolution alloys CR10 Front 18 x 8.5 ET45 = 9.5 Kg Rear 18 x 10 ET32 = 11.2 KG MRF ZTR trackday tyres Front 235/40R18 = 11.5Kg Rear 265/35R18 = 12.2Kg Total track day wheels Front = 21.0kg Rear = 23.4Kg For referance my standard set-up as it left the factory is: Rear = 25.0kg (19 x 8.5 235/35/19) Front = 21.2Kg (19 x 10 265/35/19) Total saving 3.6Kg with a swap from 19" to 18" with similar tyres sizes.

Dunc. Did you try the AD09s? I am under the impression there would be no fitment issues with 245/40 but don't know anyone that's tried it yet and that is the setup I'm looking to do on my 987.2 (CR10 + AD09)

I didn't try them but in hind sight they probably would have fitted. Cheers, Dunc
