Comments:

1. Best above improvement: .99 T-bars. Hotchkis Bilstien shocks when I went to 1.12 T-bars.

2. Least effective above improvement

3. Next improvement Likely Right Stuff 13" Front and rear disk Brakes and 17x9 rims with 275/40/17 tires. Brake ducts. 65-67 B-body rear end with oil control improvements. Front air dam/spoiler

4. Above car handles IMO on a 1-10 ( 10 best Z06, 1 yugo): 6-7. My old old hard tires stink. And my brakes are glazed over.

5. My satisfaction with handing of above car 1-10) It's never enough... 7
