Default 28" Tire question...

Sorry this probably belongs in another section, but I'm going to try some 28" slicks this weekend and I was wondering if I should even go into HPT and change the tire sizes?

Does correcting for the taller rear tire bring the wheel sensors back inline so that active handling still works?

Thanks!

Nick

Interesting question. I would not think you need to change anything unless you want the speedo correct.

i would think since your running a taller tire and you have an A4 that it will affect your shift points since your speed sensors will be calculating the wrong speed

Yep-you'll need to change it for your shiftpoints bro.

Just click auto scaling

Does anyone have any rubbing/clearance problems with 28" tires?

Yes, most likely depending on how fast you get to you will probably rub in fender liners.

If I remove the rear fender liners, would that provide enough clearance?

Some other guys and I were talking about this in the "KB runs 10's" thread so I think its good info for guys with FI cars wanting to track the car. Our questions were more of when to go from a 26" tire to a 28" tire. I run my drag pack with 28" on the streets and as long as I have 20psi in them, they don't rub. If it gets to 14 or 15psi in the tires they do rub when I hit a good bump and they bounce a bit. I have a buddy who borrowed them on his lowered car and he now has new inners, =)

If you have never had your car at the track, which would you start with if you are at a700/700 power level? The 26" or 28"?

Keith..

Minor... MINOR rub on the center of the fender [if you are looking at the passenger side of the car, the rub on mine would be at the 2 o'clock position] about 3" tall

My car is lowered almost all the way
