Description:

Quantum T5-RS Coilovers - $2100 + shipping

I've got another set of adjustable Quantum Racing coilovers.

If you don't know, Quantum is one of the premier brands of dampers out there. Here's just a short list of racing series they provided dampers for.

  • Formula 1
  • European Formula 3000
  • Japanese Formula 3000 (later Formula Nippon)
  • UK Formula 3 series
  • German Formula 3 series
  • French Formula 3 series
  • European Formula 3 series
  • Japanese GT championship
  • Formula Ford
  • UK club racing classes, including Sports 2000 and Mini Miglia
These are are all freshly rebuilt. That means all new o-rings, seals, bearing sleeves, and fresh Motul oil. As far as rebuilds go in the future, I can do them for you or it seems like ANZE Suspension is probably a good place to go to as well. These also come with new 60mm ID Swift springs. The fronts are 11K and the rears are 9K. I also included brand new Cusco upper spring perches so the top hats are fully floating. This reduces friction and bending loads as the shock compresses and thus improves reliability and minimizes hysteresis. Upper spring perches are not something you get from most coilovers--even the Ohlin DFVs lack them. These coilovers are also incredibly light.

There's a little wear on the front shock bodies from attaching the brake line to it. The front top hats are a little bent, but shouldn't really affect performance. Likewise, there is scratching under the top hats from where the springs compressed against it in its previous life without upper spring perches. As previously stated, since these shocks include upper spring perches, the spring load is now off the top hats. All this can be seen in the pictures. At the end of the day, they are used coilovers, but still in great shape overall.

From Quantum:

​​​​​​​QRS T5-RS damper is a simple, high performance shock absorber that can be internally configured easily for any track and can be tuned externally with a single shaft adjuster. This shaft adjuster can affect both low speed compression and rebound. The concept of this design is that the shaft and functional components are located on the centerline, giving them minimal operating distances. Thus the response of this damper is extremely good for higher frequency and short travel situations.
