Spring Rate 450/550

These new systems have been redesigned with improved shock dampening rates, modern foam-type bump stops, and less part content for a simple and durable sport suspension system. This is a perfect system for street performance, new track day and autocross enthusiasts, as well as project cars with engine swaps.

We now are listing EIGHT SPRING RATE COMBINATIONS for our Competition Series II (CS2) coil-over systems for these popular Honda/Acura platforms.

Here is some help SELECTING YOUR SPRING RATE combination, all are noted by (front/rear):

D-SERIES/Single cam applications

350/250
Best ride for a daily driver (DD). Great for commuting. Front may bottom out if set up too low.

350/350
Good compromise, less understeer more fun. A modest concession to ride quality. This may be choppy for some drivers with short wheelbase models; Civic Hatch and CRX.

350/450 or 350/550
Minimal understeer, quick turn-in, less roll, fast fun, good for drag launch. Rides rough on bumpy or poor roads.

B/K-SERIES/Twin cam applications:

450/350
Best ride for a daily driver. Fun and well-mannered. Modest understeer. Recommended for street/performance daily drivers.

450/450
Good compromise, less understeer, less roll more grip.

450/550
Minimal understeer, awesome handling, quick steering response, good for drag launch. Rides rough on bumpy or poor roads.

550/550 Good for track cars equipped with a front end spoiler or splitter. Also for street cars running super-wide wheels tires and low ride heights. At this point, you should know you are signing up for a huge compromise in ride quality. Very stiff!
