Coyote Gen 4X, IRS, 3.55 rear with 315 x 35 x 17 rear tires. Build is for street use only with limited long highway trips and no track.
1. Suggestions for selecting from multiple TKX ratios? Best to match with my set up and Coyote 4X
2. Bellhouse choices. steel vs aluminum?
3. Clutch choices. Kevlar vs ceramic?
4. Flywheel. cast vs milled?
5. What has been the experience with Modern Driveline, Idaho?

Thanks
