hey joey...
so it seems from my research that the bias ply avons like to be near 0 camber? is that correct? i'm having huge issues with the rivals and hoosier radial slicks due to the camber angles. i can't run enough camber to make these work in their sweet spot (front) and if i get anywhere near 1.5degrees or more the torque steer is just terrible. nearly undrivable at 1.5 and completely useless at 2. however at -0.4 i have no issues with the torque steering. i'm at -1 currently but it's still not great. i'm thinking the avons might be a big problem solver if what i've read is true. thoughts?

also...any idea what the compounds will act like? i'm looking at the 23/10.5/15 or the 23.5/11/15. the compounds are listed as medium? and the hoosiers i'm running are r80...full soft.


and finally, YES they import the cr500 canterham tire!!! so one day, i'll order those for the street tires.

I run the 23.5x10.5x15 A11 (med) they're as soft as the R80s and last much, much longer. I run -0.7 on the front and 0 (solid rear axle) in the rear. I've also ran the 21.5x10.7x15 and they worked well before I dropped the car further. The bias-ply tires don't have the same sort of response as the radials but they make a lot more overall grip.

I think that you'll find the Avon's will work well for you. The increase in straight line grip is pretty substantial. The tires don't have the same feel as radials so it'll take some getting used to but once you get to trusting the grip you'll be happy you made the switch. One thing to note, because you're FWD, you might find that you'll need to so something to brake the rear free as it might just grip too much in the back.

I thought about changing to the A15/A53 (soft compound) but on a 80+ degree day they would get greasy fast. That being said, the medium compound are pretty sticky after the first run in 40 degree weather. If I was to get a set of avons for the wet I would get the softest compound grooved out.

PS: You'll love how long they stick. Chris Dorsey did a test of a 100 run set of avons and a set of stickers and the old tires were less than a 10th slower.

i'm honestly disappointed with the hoosiers. but i think mabye...mabye i'm not getting them hot enough. there is no info at all about the recommended temps and such. and then the radial issues.
i'm hoping to get to the shop this weekend and redo the alignment settings.

You try asking hoosier for recommendations?

not directly. hoosier tom wouldn't do anything but tell me i have too much power and what not. he didn't like my tire decision. he wanted me to use a little 7 inch wide tire.

Contact them directly. They might be more willing to help. That being said. I've used Roger Kraus Racing for Avons and they've been awesome.

You try calling Roger Kraus racing? Brandon Kraus is good for answering autocross related questions.
