I like the feel and ride of my stock springs, but they are seriously rusty. I recently bought a set of stock TEMS springs and shocks from another member thinking that I was going to be able to do a quick mod to make my car TEMS enabled because I had the TEMS harness in the front of the car and assumed that it would have it in the rear as well, but when I removed all the paneling from the rear of the car the connections were no where to be found. Now, I'm considering just using the TEMS springs to replace my old rusty non-TEMS springs. I talked to our local parts dealer when I was pricing new stock springs, which were way too much, and they told me there were six different types of springs for the Supra depending on model and options the car originally sold with. If I put the TEMS springs on my car, will I have alignment or ride problems or will it not affect anything? BTW, my car is a 1990 Turbo Targa 5 speed w/ R154 tranny and LSD rear. Thanks.
