I am running in A stock just locally in my FD.
The TriPoint front swaybar, reinforced mounts, bronze busings are legal, though I am fighting the understeer.
I hate that I have to jump off the gas even momentarily to get the car to rotate at the limit- though this action has made it shoot flames through the two stock cats!
I have a ton of body roll of course, so I don't think taking it off is an option. I just keep fiddling with rear tire pressure and upping the damping on the rear GAB Super Rs, but haven't hit consistent oversteer yet.
Next, I am going to max the front negative camber to try to get more front traction.
With the K&N drop in and 3 1/2" cat back the 2ndary transition boost spike is a pain to drive around.
The C5 power and powerband just looks so easy to drive with.
From what I have read the 265 rub, though with the negative camber I have and clearance I have with 245 on I am pretty sure it isn't the top of the fender- maybe it is because they are tall/wide and rub the lower rear of the front fender?
I did Kumho last season and will try Hoosier this season.
Last time I looked there were not many people running A stock nationally, so I would think a great driver could be competitive in any A stock legal car. Go go go.
