    Re: oversizing tires on turbo

    I got myself a set of PZero Corsa racing compound tires sizing 235/40/18 front and 295/30/18 which I will try out on a track-day next week. I'll keep you posted on my experience .

    Re: oversizing tires on turbo

    Good man, Phil. I guess this post just couldn't arouse too much excitement; but until I find out otherwise, I guess there are some 315's comin' for my rear. The 235's ought to be of some improvement as I am able to easily spin-up the stockers coming out of a second-gear canyon turn.

    From what I recall the Turbo needs its fenders rolled in the rear, when the car is lowered and using 315s. Besides that, there are NO Problems with this tyre combination. A guy called Chad from the Bay Area is running 275s and 335s on his Turbo, with heat-gun-treated wheel wells and some radiator reshuffling (really a minor job).
    You should visit 6speedonline.com. They are more into modifying their cars with wings, etc., but will have some good advice for you.

    Re: oversizing tires on turbo

    KG1-

    I can't comment on fitting the tire sizes you mention on stock wheels. However, I ran a complete GT2 wheelset on my 996TT (ROW sports suspension) with no clearance problems at all.

    Re: oversizing tires on turbo

    I did a track-day with PZero Corsa tires sizing 235/40/18 front and 295/30/18 on stock TT rims - No clearance problem whatsoever .

    I would hope not as those are stock sizes.

    Re: oversizing tires on turbo

    Stock size is 225 at the front.

    Re: oversizing tires on turbo

    I stand corrected! My bad.

    Re: oversizing tires on turbo

    What was it like with 235's Phil?

    While on stock PO Asimetrico's in 225 the car feels rather "oversteering", these Corsa's in 235 give a very solid feeling to the front wheel (better grip + more committed steering) and much reduced oversteering tendency, even with cold Corsa's. Although I have no pretention to put in question PAG engineering wisdom subjectively I would be tempted to say it's maybe a better combo for the 996 TT

    I'm not sure if I know what you mean, do you mean...by comparison with the OEM 225's the 235's feel much better and promote a lot more eversteering? I sure hope so, since I ordered a set of 235's/295's Michelin PS2's...

    Re: oversizing tires on turbo

    I'm rumming 315 rear and 235 front PS2's on stock wheels with no problems. They are smoother and quieter than Asimetricoes.

    Re: oversizing tires on turbo

    Kiko,
    Sorry for delay in answering, yes I meant that compared to the 225's 235's seem to generate less oversteer. Of course I do not have hard data (it's nonsense to compare a Corsa to an Asimetrico), but definitely the front wheeltrain feels much more "planted" on the road.
