Hi, just a couple of questions for you guys.
It time to change the rear tyre on my 95 f3, I have a 160/60/17 on the rear which I believe is standard, but the front is a 120/70/17! I know the standard front is 120/60/17, am I gaining anything by the higher profile on the front, or should I put the correct tyre on when I change the rear?

Also I have a k&n filter fitted, but have heard a few times that it will make it worse, is this true or should I fit a standard filter? I have ss nexus exhaust with down pipe as well!

Thanks Pete

 

The general consensus seems to be that either a K&N or a slip on is okay, but both together should probably prompt a re-jet. I'm sure one of the gurus can give you a more detailed answer.
