Track results from Suspension mods

OK...So I boxed my LCAs, Panhard and TQ Arm. Installed Polyurethane bushings in all those parts and went to the track today.

Last years 60 ft :2.04-2.19 (all stock suspension)
This year 60 ft: 2.14-2.44 (cold track, 2nd day open, a light drizzle, more power)

Now last year I ran on a regular track day so there was decent hookup, also I am making a little more power this year due to the custom Prom and no Cat(@20-30HP).

Today the track was not hooking and it was actually drizzling a little bit so I am sure that the slower 60ft times can be much improved.

I ran 2-3 Mph faster with a strong head wind today vs. last fall.

I believe that if I can reproduce steady sub 2.1s 60 ft times this year that should move my car in the the sub 14.5 range. I ran 14.7x all day today @93MPH today. Last year I ran 14.90-15.1@90-91MPH

One thing is for sure...the car is feels real tight! And wheel hop is gone!!!

Maybe try some LCA relocation brackets for some added help. Cheap and easy to do.

Sounds like some good times.
