Just here to say, BC and Tein are budget coilovers.. far from quality, let alone high quality. I also wouldn't look for used budget coilovers since they don't last very long. They will surely need to be rebuilt by the time you get your hands on them.


I highly recommend looking into good springs and struts instead. Springs and struts will out perform any sub $1500 coilover. If you really do want high quality coilovers, I would choose between KW v3s and RCE Tarmac 2s. The KWs should have a little better ride comfort, whereas the RCEs should perform better on the track.

It depends on how comfortable vs. handling performance you want. Progressive rate springs and lower spring rates will provide more comfort.. linear rate springs and higher spring rates will have a rougher ride, but will handle better.



Eibach Pro-Kit are a good comfort oriented spring with progressive rates (front 174lbs/in-193lbs/in --- rear 94-161lbs/in ---- front drop 1.3" --- rear drop 1"). I've had these on my bugeye for many years with KYB AGX struts. They are pretty comfortable to drive on, a little stiffer than stock. The drop front vs rear on these will basically make the car sit level.


Swift Red are a linear rate spring (front 185lbs/in --- rear 151lbs/in ---- front drop 1.2" --- rear drop 0.6"). These could also be used with the KYB AGX struts.


Epic Engineering, I'm not finding the spring rates for these so hopefully someone else can chime in. I just remember they are good quality (front drop 1.6" --- rear drop 1").


RCE Blacks are a great choice if you have performance in mind (front 275bs/in --- rear 250lbs/in ---- front drop 1" --- rear drop 1"). KYB struts would not hold up well to the spring rates of these, so I would run Koni Yellow inserts with them.



I think for all those options the Koni inserts (you cut your stock struts open and replace the guts) would be a better choice (at least performance wise) than the AGX struts. However, AGX struts have four way adjustable dampening.. the first setting it fairly soft, and the fourth is fairly stiff. I like having them on #3 with my Eiback springs, but #2 isn't bad either if I want it to ride a little smoother.



With any of these spring/strut setups I would get Whiteline Comp C tophats to go in the front, and Group N tophats for the rear.



Pretty much all of the budget oriented coilovers are going to be super harsh and bumpy. At one point I had Tein Flex coilovers and every time I hit a bump it would cause a shooting pain through my lower back. If cornering hard on a road that wasn't perfectly flat the rear of the car would actually bounce and lose contact with the road from time to time, which is not going to get you around a corner very fast, and could be hazardous depending on how aggressive you're driving.
