I've now got the larger Pirelli PZero Corsas fitted - 235/40x18 front on 8inch standard rims & 295/30x18 rear on 10inch standard rims. The tyres are superb ! Grip is unbelievable compared to the previous "standard" Pirelii PZero Rosso's (which seemed good compared to experience of these on my previous BMW M3s). Even with the PSM switched off & trying to provoke them causes no loss of grip (in the dry) - whereas powerslides were easy in 2nd gear with the Rosso's. Very mild understeer of the standard C2 appears further reduced & the old saying "corners like its on rails" definitely appears true ! Grip in the wet appears absolutely no problem - don't even have to think about it - whereas I've heard bad things about Michelin Pilot Sport Cups - unless they're warmed up first. Very minor noise increase compared to the Rosso's, but ride quality has improved slightly over ridges, small bumps etc (probably effect of slightly taller sidewall on the larger width (+10mm on the standard tyres for my spec.) OR maybe softer sidewall) The tyres appear very round / easy to balance - as there is no steering wheel wobble at any speed (achievable on UK roads !). The increased width front & rear does not cause any rubbing with arches on bump or cornering. It appears that at least another 10mm width increase is possible without concerns - as suggested by another poster. Biggest cause for concern is rarity - I could only source these tyres through 1 of the local OPC's. The OPCs pay Pirelli more than "normal" tyre depots so that they get preference. If I hadn't gone via the OPC, all other depots were telling me that they could only get 3 tyres - without any known promise date for the remainder because of manufacturing backlog / low priority in Pirelli Europe. I can't wait to try them on my next Track Day in a few weeks. Enjoy your cars ! Paul 2004 C2 Anniversary (345 Hp engine, M030 suspension, LSD, 18 inch etc)

Smackboy, thanks for the response, the fronts were more of a concern than the rear due to the steering movement. The rears appear to have lots of clearance around them. Thanks for reminding me that the C4S has the wide body not the "basic" C4. I think the tyres will be on the car next weekend ! Paul

Has anyone got experience of using 295/30x18 rears with 235/40x18 fronts on a 996 C2 Coupe ? I've got a 2004 C2 with the standard 285/30x18 rears & 225/40x18 fronts & want to improve dry grip by fitting Pirelli PZero Corsa's - which I believe are a better compromise than the Michelin Pilot Sport Cup tyres for mainly road use - but with occasional track day outings. (Everything I've seen suggests the Michelin Cups are a better track tyre - but need more warming up than the Corsas) My existing Pirelli PZero Rosso's are about worn out - so now's the time to have a look at the options ! Unfortunately the Corsa's are only available in the slightly wider 295 / 235 widths (as fitted to the 996 GT3) - so I want to be sure there won't be fitting problems before I order them. I've read on other forums & in the Renntech forums where owners have fitted the GT3 tyre sizes that they fit without rubbing on inner or outer wheel arches (front or rear) - albeit on wider rims than the standard 10inch rears / 8 inch fronts that I have. As the GT3 uses the narrow C2 body without wheel arch modifications if I understand correctly, it would make sense that they should fit without issues. Has anyone direct experience of using these tyre sizes on a C2 & if so were there problems ? I don't think C4 fitment is relevant as the wider rear I guess should result in no problems. Thanks for any input - Paul 2004 C2 Anniversary (UK (RHD) spec C2 Coupe including standard 345 bhp engine, sports suspension, manual gearbox etc)

I have a 2004 40th Anniversary C2 996 (absolutely great car with the 345 bhp engine & sports suspension !) & being a really mean individual, I bought a Porsche roof rack to carry mountain bikes etc rather than needing a second "practical" car. My problem is that to fit the roof rack mounts, you have to remove the plastic (I think)) blanking screws that fit into the mounting area under the folding flaps in the roof strip. After carefully placing these in various "secure" locations on the number of occasions I've used the roof rack I got complacent & placed them somewhere & now can't find them. As the screws prevent water getting into the thread area - which is unpainted - I definitely need replacements. I've tried the local Official Porsche Centre & after more than 8 weeks of alleged dialog with Porsche UK they can not identify the Part Number of the screws - which appear common to the 996, 997, Cayman & other models (based on isnpecting various cars in their showroom !). I've reviewed the official Porsche Parts Lists available on-line for the 996 911 model & I can also not see any reference to the screws anywhere As mentioned elsewhere in the renntech forums, these screws are obviously installed before painting the body as they are body paint covered & the paint can make them difficult to initially remove (very good fitting flat blade screwdriver seems to be the answer). Can anyone help identify the Part Number of these screws ? regards & thanks in advance, Paul
