Mugen Sport Suspension Kit – Type “R” version for 06+ Civics
I have been doing some digging on the Mugen Sport Suspension Kit for the Civic Type "R". Based on the info I have pulled from King and Mugen Japan, this is what I have found when comparing this kit to a OE Si suspension
Spring Rates:
OE (si)
(Front) 200 in/#-- (Rear) 230 in/#-- Spring Rate Stagger 1.15:1
Civic Type R (FD2)
(Front) 294 in/#-- (Rear) 345 in/#-- Spring Rate Stagger 1.17:1
Mugen “Type R” Set
(Front) 271-290 in/#--(Rear)367-390 in/#--- Spring Rate Stagger 1.35:1
Spring Rate Increase (Si to Mugen Type “R”)
Front-------------Rear----------------Stagger
35%-45% -------60%-70% ----------18% increase
Damping change of Mugen over OE Type “R” rates
High Speed damping - small increase F and R
Low-speed damping – Substantial Decrease front, Slight increase rear
BUT Should be a fair bit higher damping rates over OE Si Rate
Lowering
-10mm (0.4”) Lower than OE Type “R” ... about 0.75-1" Lower than OE Si
So we get substantially higher spring rates, with a fair bit more rear spring rate stagger. This should minimise the built-in understeer and make the car more neutral. The changes in shock valving should also help this while maintaining reasonable ride comfort.
This on the surface appears to be a VERY interesting option as a "street" setup untill Koni finally decides to play in our sand-box with OTS Sports (Yellows) as you have a good spring rate, good F/R stagger, and matched shock valving
Any thoughts on the above ?
