Front clip
I bought my TCI fron clip through one of THEIR dealers, Stitz Street Rods. Stitz has gone out of business and did not get me all the parts in the clip kit (missing the sway bar, shims, grease seals, brake booster bracket, wrong caliper mounting plates for the Wilwood brakes).
I called TCI and they were happy to SELL me a sway bar ($300+) and the correct caliper mounting plates ($200+). They would not help me with the brake booster bracket or grease seals (told me to contact the mfgs of those items). They also said they have changed the design of their brake kit so I am stuck with a power brake booster (probably another $250+). They have sent me the wrong caliper mounting plates twice now and I plan on heading up to their shop to try to get the correct parts (my heart can't take the UPS guy showing up with a TCI box anymore).
So, I have had a very expensive experience with TCI and their interest in follow through with their customers seems really low on the scale.
I am trying to get to the point where I don't have to deal with them anymore but I do need their parts to finish.
You can probably guess what my recommendation is for using their stuff.
