Alright Supra Celica, I will do what I can here. I do not know of many other brands, but I know what is trusted/reliable from other owners.
1. I recommend Tom's. Any flywheel will work, as long as its for your car.
and Trial headers are your best choice. Look around for Dynos, I think trial had better results. I don't know about the ceramic
3. Tein and Sportivo are really good. If you want coilovers, also Skunk2. Or you could go with springs and shocks, that will be a little cheaper. Go with well known brands (Eibach, Goldline, Toxico, KYB)
The things mentioned above are expensive, because they are the best. Do not settle for anything cheap, aka. ebay. Make sure when you mod you do it right. Thanks for asking around man. I hate hearing about people that just jump into things without researching.
Places to search: you can check out other forums,
titanmotorsports usually has low prices (don't know how reliable they are)
afsmotosports- I like them, they may not have what you are looking for though.
I don't really know a whole lot on where to find your products, I don't have as many options as you, I have a GT and I haven't got to the suspension yet. Peaceout man.
