Yeah, I know of that west coast drive. Im in that region. Dont know him personally, however. Parts are a little hard to come by, thats for sure. The fact that you can get a real limited-slip is good tho. I know that coilovers are hard to come by because of a funky design on the rear shocks. There is a tech article on this website that talks about how to make external coils fit:

There is also some info about suspension mods for these cars in general. One thing that I had thought about doing was contacting the guys at the Danny McKeever racing school. They use former Long Beach Grand Prix celebrity race cars that have been Toyota Celicas for 20 years. This is the school that the celebs to go before the race. They are Toyota people and may have some good info.

The only real problem Im having with the Celica right now is that my partner in crime, the dude who has all the mechanical skills, HATES FWD cars. Dagnabit. Anyway, let me know if you are gonna do the petition. My email is [email protected]
