20inch wheels on 997.1 turbo

[greyporkerTT]

I am new to the site, thus i suspect that the topic has been discussed before so apologies.I am considering changing the stock rims on my 997.1 Turbo to 20inchers. Does anyone know the most suitable front and rear tyre configuration and rim offset for the front and back axle? I have read reports of problems with front diff damage as a consequence of inappropriate tyre dimensions.

regarding the overall suitability of moving from 19 to 20, all opinions and experiences are greatly appreciated.

I am running

20x8.5 ET42
20x11 ET55

Fronts look very flush, i am getting 15mm spacers for the rear to make it more aggressive. I actually liked the standard alloys (well they gre on me) but a personalised touch is always better. It's been lowered on H&R spings as well,

Wow they look amazing. What are they? With lower profile tyres are they the same circumference?

Ispiri FFR6,

Tyre profile went from 40 to 35 so not too much in it. Ispiri have some cool designs as well, without being bank busting
