anyone know the ideal tire pressures for running on the 03-04 coupe's oem 18inch tires for b-stock class?

 

I ran +2 PSI in the front on Pilot's last year. I added a hotchkis sway bar upfront and was getting killed with understeer. Running 37 front and back would be ideal with stock sway bars but you will have a lot of understeer. Without auto-x tires it wont really matter because someone will have them and that will be a big difference.

FYI all tires respond to pressure differently. a Pilot's ideal PSI for the street or track are going to be way different from a Hoosier so the best bet is to do some testing. I started all the way up at 40 PSI my first auto x and came down from there by monitoring tread wear between runs.

 

yeah i was just wondering what everyone else was using i was running 42 front 37 rear and had no problems

 

I ran 38-40 last year in my pilot sports.

this year i have:
goodyear f1 supercar 275/40 r17 on the rear, so I will have to start over
pilot sports 255/45 r17 up front " "

I see you're running 17s all around, I'm assuming you had 18s stock with the Brembo brakes, is that correct? I've been wondering if 17s would fit over those brakes as I've been considering going with 17s for race rims to enable me to effectively "gear down" and save a little money on tires.

Anyone have a good 'bang for the buck' suggestion for 17 or 18 inch race rims that fit an 04 coupe? I really don't care what they look like as they're for the track.

 

i believe if you switched from 18s to 17s that might take you out of b-stock class

 

no brembo's for me... 2003 auto coupe. plain-jane stock brakes.

i've been looking at 5zigen rims, you can get them for about 210 bucks each.

5lbs lighter than stock.
