Hi everyone , I am interested in doing trackdays with a 200bhp 2.4S engined 911E fitted with 15 inch Fuchs wheels - 6 inch rims on front and 7 inch rims on rear. Its also fitted with uprated clutch , 915 box + LSD , uprated suspension so should be able to cope with the excitement. No ABS of course.
Current road tyres fitted are Pirelli P6000 , sizes 15x 195/65 and 15x 215/60 respectively.
For 'sticky compound' road legal track tyres I have used Toyo R888 on my 964RS and I like the grip they give , however the available 15 inch sizes are limited to: 195/50; 195/55; 205/50; 215/50; and 225/45.
As I understand it , if I were to go with the 195/55 size on front 6 inch rims and 215/50 on rear 7 inch rims , the result of the Toyo's lower profile would be 107.25 / 107.5mm sidewalls compared to the Pirelli's 126.75mm / 129mm sidewalls , effectively lowering the car by 20mm ? Would there be any adverse effects of this , I can see benefits eg lower CoG.....
Has anyone tried modern lower profile tyres or road legal 'grippy' track tyres and what was the result / recommendation ?
PS I know cut slicks are not wonderful in the wet but I dont think the car will be going out in the wet much ...in deference to its great age and a desire not to encourage corrosion more than is necessary [
