I guess first off I should say I,ve already got coilovers and they are in good shape but seem to be attached to the stock top mounts.

Are there any adjustable strut mounts available from aftermarket companies separate from their full coil over systems

Are the st205 top mounts the same as the lower trims?

Along the same lines what are options for wheel bearings. I figure with 160k km now one should be coming up. IF my experience with how many bearings I went through on my st185 is any indication.

The top hats should be the same for all Celicas from 86-99.

That being said, if I was going to purchase top hats only, I would go with the TechnoToyTuning units.

I can't speak to the wheel bearings.... Although I should look into it, my 205 has 177,xxx km....

i bought a set of wheel bearings for the st202 superstrut from UK Ebay. paid $70 shipped i believe. but that was 4 years ago.
