Each TPU set is built-to-order so valving and spring selection are matched to your exact Porsche 944 (Late model) 87-91 (NA) 86-91 (Turbo) application, with the same 32-level damping adjustment and full-length ride-height range you”d expect from the Riaction platform. For LATE owners chasing a track-focused setup without giving up street composure, this LATE coilover kit bridges the gap between daily driver and weekend warrior.

TPU vs GT1 — Which Is Right for You?

Both kits share the same 52mm monotube damper body, 32 levels of damping, full-length ride-height adjustment, and spring rates. The difference is in how the damper reacts:

Short version: choose GT1 if you want the best daily-street-track balance and ship-ready. Choose TPU if you want tighter response under load and don”t mind the lead time for a digressive tune.
