who makes the best suspension? I'm thinking bilsteins with eibach springs for .8'' drop, probably mostly an autocross car.

 

they are both good manufacturers, Tein has different setups depending on the application.

I'd also choose a full coilover setup over a spring/shock mix match combo.

 

I don't understand the differeve of strut/spring vs coilovers? Who do I buy coilovers from?

 

Bilstein makes coilovers as well, I myself am more of a fan of Bilstein.

Everyone sells Tein, but the more hardcore race shops will sell Bilstein stuff, especially shops that specialize in BMW's.

Another awesome setup is Ground Controls with Koni Yellow shocks, a lot of SCCA racers run that combo.

Only big reason to go coilovers is to have the height adjustability for corner weighing the car. A lot of people think they need full coilovers, they don't. I would run that eibach/bilstein combo, and if you need coilovers, just get the ground control sleeves in the future.

 

I like the idea of bilstein I just need to know where to get full coilovers by them, it only gives me one choice for suspension products. 87 RX7 NA.
