i have a '72 pantera- engine mods to 400+/-hp-- need advice on tires/wheels-- plan to go to 17" - what front/rear combo will give the best handling? i have been told to go with 245/40/17 fronts and 315/35/17 rears-that both will fit standard wheel wells with a small amount of the rear tire protruding. i was also given advice to go with 225/45/17 fronts and 275/40/17 rears- this may be more art than science, but any advice appreciated

For handling, low rideheight and some lower front rake is imperative. Also, we need some wheel spring travel. The extreeme setting will need a 21,5 inch diameter front tire.
Look at my car at http://hem.passagen.se/hemipanter/
Here I use a 23,62 inch front tire and a spoiler to ground height of 4,75 inches. Works Ok. but when lowered to 4 inches those wheels hit fenders at hard braking-cornering.

However, a 5,5 inch front setting may clear a 24,5 inch front tire under hard driving conditions.

Everything in between is on a linear scale, from cruising to racing. Rear ire size is not a big problem.

Besides that the best tires are har to find,
I should recomend a 23,62" diameter front tire an something like 25" at the rear.
