Advanced street car group at the Shelby National Convetion track weekend.

2003 XJ8 with Bilstein Greens, Mina Springs, Powerhouse sway bars, all bushings replaced and Toyo RA1s 255/55/16

 

nice video, thanks for sharing

 

Yes, thanks for sharing....did you shift with the J-gate or just leave it in D? Sonoma is a track I'd love to drive.

 

Shifting using J-Gate. Mostly 2nd and 3rd, never hit fourth, nor needed first.

 

Looks fun!

 

So you have your best lap and top speed?

 

what are your thoughts on the upgrade?

 

Did the Power House sway bar help with the handling?

 

All the pieces together worked great. Only issue was over heating power steering fluid. The handling was almost perfect. Very neutral and easily throttle steered. More steering mid corner in longer turns induces oversteer without lifting throttle. Brakes were my biggest concern but were wurpringly good. Here are the things done to get this set up working and hardened:

1. Replaced all engine gaskets and seals.
2. Replaced plastic thermostat and all possible plastic cooling components with metal.
3. Replaced all subframe and steering rack bushings.
4. Mina springs.
5. Rear springs packed to raise rear for ideal rake and better turn in.
5. Bilstein HD plus sports ( green ).
6. XJR rear subframe and differential ( to mount sway bar - stupid expensive ).
7. Powerhouse rear swaybar.
8. EBC Yellow brake pads.
9. Motul RBF 660 fluid.

The car is a beast and alot of fun.

 

 

Im planning on developing this car now since it held up so well. Next up are sub frame braces, strut tower brace, 400mm monblock brakes, wide square tire / wheel setup with custom offset ( ~275-305 ), power steering cooler and custom reservoir, and maybe muffler delete but only if it passes sound levels at Laguna Seca.
