Winter changes on the AMX. Are you going to make any changes on your race car?

I'm going to combine a few different things. Please bear with me.
1. Going to install a vacuum pump.
2. Going to install a oil accumulator.
3. Going to put stiffer springs on front and re valve the front coil overs.
4. I got a really good deal on a new set of 14.5 X 32 X 15 Phoenix radial slicks.
5. Going to put some Phoenix front runners on.

Does anyone have experience with the Phoenix radial slicks?
Phoenix radials are very good tires. Are you switching from a bias ply to a radial? Or do you already run a radial?
