SOLD OUT. Gauging interest in another run.
4/8/2021 UPDATE **** We are getting close to another run. Please let me know if you’d like a set, and if you would also need the spring perches. Send me a message here.

For the Acura RSX (DC5) and Honda EP3
The stock caster is one of the biggest alignment issues with the RSX . The factory specs call for 1.5º caster +/- 1.0º So you can have only one half degree  of caster and be within factory specs. What caster does for you is add dynamic camber.

When you add static negative camber (angle the wheels inward at the top) you increase the tire contact on the outside tire, in a turn (this is great). Unfortunately you loose tire contact area on the inside tire (not that big of a problem), but you also loose tire contact area for accelerating and braking. That is a step in the wrong direction. When you add caster, you can run less static camber for more traction to accelerate and brake and the more you turn the wheel, the more outside negative camber you get and inside positive camber you get. This is why they call caster, “dynamic camber”. The more you turn the more you change the camber the way you want it. More caster is faster!

Add 1.65″ (42mm) of caster.
Adjustable Camber – Add .173 to 1.06″ (4mm to 27mm)

Caster / Camber Plates $468
Upper Spring Perches (2.5″ or 65mm) $70 pr (Most high end coilovers have these so you will not need to order them, but we know these work perfectly with our plates)
Option camber adjusting tool $16
Extra or replacement shoulder nuts and spacers can be purchased for $42
