New release : TC Kline s/a and d/a coil over suspension kits for F8x

Looks like tc Kline has just released their standard single adjustable (23xx.xx) and dual adjustable (30xx.xx) kits for the F80 platform

Good to have another competing product with linear springs

My key question is on the d/a kit, how much shorter than stock are the shock and strut bodies and at what ride height are they ideally designed for and will have the most shock travel?

Interesting addition to the market, and id take a d/a kit over a kw v3 with random non published progressive spring rates but jmo

Sweet! I like the price and the ability to pick your own spring rates.

Both the TC Kline Racing struts and shocks have 1" shorter bodies for added compression travel.

Spring rates recommendations are 350 front and 600 rear or 400 front and 700 rear depending on what you plan to do with your M3/4.

These wider than stock? I only have about 3mm of clearance with the stock setup between the wheel and spring.

What is the difference between the two sets of spring rates? Is higher better for track or street? What are OEM spring rates?

Stock spring rates are 185lb/in front and 575lb/in rear. If you track a lot, then go with the higher rate setup. It's not as comfortable on the road, but manageable. The cool thing about TC Kline is you can go with a different spring rate if you hate it.

Single Adjust for road use and light tracking. Double if you track a couple times a year.

I wonder how the D/As fair against the KW Clubs. The best part is the spring rate of your choosing.

Those who uses K&W CS swears by it. Those who uses TC D/A swears by it. Both have lifetime warranty. You can't go wrong with one or the other. Cool thing about TC is you can customize your spring rate. K&W rides slightly better on the street with the helper spring.

I have customized many KWs, v3 and particularly CS, including shock valving; have they changed their policies?

Where do you buy your K&W from? I was under the impression that only the EU market gets to pick their spring rate. I haven't asked iND, which would be my vendor of choice for K&W.

Our experience has just been the opposite. The KW CS rides much firmer than TCKR DA's.

TC D/A with 400 front and 700 rear? Interesting

Spring rates do not impact ride quality nearly as much as shock damping and suspension travel. While I don't have TC Kline coilers, 400/700 is not that stiff at all.

Consider the fact that Swift springs, which people claim ride very well, have rates of 280/730 on stock shocks with no shortening of strut body for more suspension travel, not properly matched dampers, etc. It is easy to see how KWs, with properly matched shock travel and shock damping, can provide good ride quality with even seemingly stiff springs.

TC Kline comes with cambers. If you don't track it, then there's not a need for camber plates. You can't go wrong with K&W V3, Bilstein PSS10, or TCKR S/A.

KW CS and V3 you can customize spring rates. KW CS is just the std. 60mm Spring IIRC. But the V3 needs a conversion kit(at least on the E92)

JRZ's for me if I was doing DA's. Truly customizable, easily serviceable, and great support.

But the more choices there are in the marketplace the better.

I am sorry I just saw this, I must have missed the notification. I used to get them direct from KW. It does not make sense that only EU market gets customized springs and shock valving. Who rebuilds the shocks? KW US or CA does, they have the equipment to adjust valving to any desired values, including the spring rates; otherwise why would you even get the standard 2.5" ID springs?

The only challenge I can see, most people may not know how to ask for custom valving, that's the added value that retailers and distributors should provide IMHO.

This tells me that you won't track your car, which is of course quite alright. However if you will not, why would you waste your money on coilovers? Huge waste of money dmk.

Thanks for your concern? Plenty of people who never track do coils. Best way to lower the car. But fyi I am doing Road Atlanta June 8th.
