so no ones' got any data to prove that going wider in the rear can benefit a V8???

yes, it will benefit the fact that it will be harder for you to spin the rear tires, which is plenty gud in a v8 914 as you don't want to spin the rear while you're in anything BUT a straight line ...

as for the overall balance, a large difference in tiresize rear/front will throw off your otherwise good 50/50 balance of the car.
with much bigger tires in the rear you will add massive understeer in corners. you *can* compensate for that with bigger torsion bars and a BIG sway bar.

it's all in the (corner) balance.

Pirelli hasn't made that size in 15 years!

if you got those tires "new" make sure they're still soft as they must have been sitting on someones shelf for over a decade ...

i'm sorry, i didn't mean wider rubber in the rear, i mean wider stance via spacers in the rear.... whoops.

wider stance through spacers won't give you more traction.
if balanced with the front (bigger torsion bars, large sway bar) a wider track *will* improve handling ...

the wider the better, *if* balanced with the front ...

mueller mentioned scotts race car. it actually has a wider track in the *FRONT* ...
