Have you considered an aftermarket UCA/LCA?
Well, no. But, I had an '85 and then '92 VW GTI. The '92 was lowered, lower diff, short throw, Tokico adjustables, cam and intake, chipped, top and bottom Neuspeed strut braces, subframe X brace, Alpine system with built in Stillwater box against the seat back, Yokohama soft composite rear with Dunlop GT fronts, etc., etc., and several suspension upgrades with polyurethane. It owned every autoX it ever attended, except one guy in a f'ing Miata.
The poly can get loud, loose, and hard feeling, especially on a MacPherson strut setup or similar.
For driving around like normal, I want stock. I am very particular about having performance at any cost if racing a car, but I want quiet and subdued communication through the car, from the road to my hands, while I'm driving streets. A quiet yet tight suspension is the epitome of a quality road car to me. Screw the seats. Screw the leather. Screw the chrome. Quiet and tight sport suspension is where it's at for me.
All that said, what's the best LCA brand in your opinion?
