This may be a stupid question, but i don't know so i'm going to ask. Last year we ran the hoosier tires. sizes 86 1/2 and 87. Thats the size we were told we should run. At the track we noticed several other guys running different sizes, say 85's. Other than needing the different size for tire stagger would there be any other reason for using different sizes. The only thing i can think of is engine rpms.

If you do your ride height from the frame to the ground it will change the front control arm angles and your rear link angles.

traction the 26 are better than the 27 put 10pd of air in both sizes and look at the tire footprint then you will see

Im saying if you set your front ride height at 6" from the ground to the frame and you have a tire that measures 87" and then you put a tire that is 85 or smaller and set your ride height again, you will have to screw in on the jack to get your 6" which will change your angle on your control arms, same thing with the back. and back link angles are a big thing

He is right on the ride height deal i check mine off the lower control arms and when i change tires i check it again to get the same angles back
