KW V3
- Pros: Best compromise between street and track, lifetime warranty, adjustable compression and rebound
- Cons: Noisy over moderate bumps, slightly stiff for some passengers (even on softer settings), can't reuse rear shocks due to o-ring modification

Mazdaspeed coilovers (MS3 variant)
- Pros: Valved for track use, adjustable compression and rebound, cheaper than KW V3
- Cons: No lifetime warranty (can be serviced by KW for $100 per corner), stiffer rates are a bit stiff for street use (though not uncomfortable), noisy over moderate bumps, can't reuse rear shocks due to o-ring modification

H&R SPC's
- Pros: Inexpensive, valved for street use, lifetime warranty, progressive spring rates, can be custom valved (parts are widely available)
- Cons: Too soft for frequent track use, no adjustable compression or rebound, harsh if dropped lower than 2"

BC
- Pros: Inexpensive, upper mounts included, adjustable compression and rebound, rear shocks have adjustable height without loss of suspension travel
- Cons: Very little compression adjustment, non-linear dampening, spring rates are a bit "harsh" compared to progressive springs, some concerns in the community about quality/reliability
