What pressures for road and track in Pirelli Corsa on C2S?

[Gibbo205]

Hi there


Fitted some Pirelli Corsa N1 tyres today from a GT3 on my 997.1 C2S, they are 235/35/19 and 305/30/19.

I believe Porsche/Pirelli recommend recommend 29psi front and 31psi cold pressures, can anyone confirm this please?

But a GT3 weighs 1395kg, compared to my C2S which weighs 1430kg along with different tuned suspensions, though my car does have GT3 roll bars, LCA's and is running a fast road / track geo.

Should I also go with the same 29/31 cold pressures in my car or maybe something a little high, maybe 30/33 cold?

Lastly at the track what hot pressures should I aim for with these tyres?

P.S. Also fitted a set of OEwheels TPMS sensors and can confirm the work fine and at £150 far cheaper than the £500ish Porsche wanted.

With those fitted to my GT3 I used normal road pressures but when HOT. Gave good grip and even tyre wear

Were they 29/30 or 29/33 m8, or did you use something different?

Whatever it states in the book or the sticker in the door shut. 29F 31R rings a bell but I could be wrong. Definately remember the same as oem pressures but hot instead of cold though.

My car is a C2S so door shut pressures not right for such a tire.

I started with 31/36 cold but felt a bit odd.

Tried 29/32 cold and they seem superb at that, I now understand why the GT3 rave about this tyre, very very good indeed, even better than the MPSS in the dry and feedback along with turn-in is superb. Can't wait to get on track now with these!
