The guy I bought my SPF from had autox'd and road raced it quite a few times from the sounds of it. Besides a WHOLE LOT of suspension adjustments, he added a few other mods to make the cobra work better for autocross and road racing.

- Tilton 7.25 Cerametallic twin disc clutch which allows slippage much more than a normal race clutch.
- Quartermaster 153T flywheel, lightened to 8.2 lbs/3.72 kgs allowing revs to come quickly and are there when you want them.
- Tilton hydraulic throwout bearing
- Pro 5.0 shifter (MUCH better than stock for quick shift changes)
- Torsen T-2 Traction Differential
- Replaced ALL suspension bushings with Spherical Bearings
- Blistein adjustable coil overs with better springs.
- rubber/front: 17x9.5 275/40ZR17 G-Force KD
- rubber/rear: 17x11315/35ZR17 G-Force KD
- custom built 4 point full roll bar
- ATL 17gallon fuel cell (more for road racing)
- Custom built EFI induction system controlled by a MegaSquirt ECU

These changes make the car super sharp in cornering and exit, but do not take away TOO much of the comfortable ride (its no caddy). I have noticed little to no bumpsteer as well. He mapped the entire SPF suspension geometry in CAD and worked constantly on configuring it. All of these changes allow much more nimble control and even with an all aluminum 427W from Keith Craft, allows the car to run around pylons well (according to previous owner). I have not tried it yet as I have spent this whole time trying to get used to the car. Another SPF owner that just moved from Ohio recently to my neck of the woods went to an Autocross this weekend with me to take a look. I think he has convinced me to get out there and run it around the course. Basically boiled down to "what are these cars for anyway?"
