TCK D/A Spring Rates

I am currently running 400/500 springs but feel at the track I can use a stiffer set-up. Anyone running the TCK D/A on the Mcoupe and tracking? If so, what spring rates are you going with?

This is Two months after your post, but I have a 3.0i with 550F /700R and it is awesome. I primarily autocross, and use a square tire setup also.

I have 500# front and 600# rear on my TCK DA suspension. The key to a manageable street ride is proper adjustment of rebound and bump. I run two clicks in from full soft on front and rear bump and 1.5 turns in from full soft front and 1 turn from full soft rear for rebound.
For a dry track I run 8 clicks from full soft front and rear bump and one half turn from full firm front rebound and one turn from full firm rebound rear.

Thanks Jim - I was looking at swamping the springs out to 500-600 but I may hold off and look into the moton set-up for next season. Did you swap your sway as well?

Hmmm maybe we could work something out because I am looking at going with the 600/700 set up. I currently have the 525/650 set up

They should be able too. Both TCK and GC use the same Koni shock I believe. I guess he only variable is what TCK valves their shock too. I guess the best person to ask would be TCK

Yea I know for the TCK they use the vvs springs but the koni shocks can only handle I would think max 700. Would be interested to here what TCK has to say about run that type of spring rate on the m coupe.

I had the TC Kline 500/600 and it was way too soft. I eventually ran 550 front and 700 rear, but then it began over springing the dampers. I got rid of mine and threw them away.

I had 800 lb rear springs on my E46M3 and the TCK DA shocks seemed to work well with those springs; however this was primarily on smooth racetracks not nearly as demanding as the Nurburgring (which I believe is RussRamz playground) so I believe that for autocross or most US racetracks they are OK at up to 800 lb spring rates. During a conversation with Pete at TCK a few years ago I recall he said that they don't sell any springs higher than 700 lbs, but he didn't say that the shocks can't handle a higher spring rate. Hope that helps. I haven't done a full suspension on my Z4MC but I think that 700 lb springs in the back is as high as I would go. I cannot speak from direct experience however.

I have a custom 2 way KW Competition setup. They cannot be ordered off the shelf, but it's quite easy to have a set made and delivered if you're willing to wait for them to be built-up (2 weeks) and shipped (another 2 weeks or so if shipping stateside).

Anyone have experience with the Moton clubsports on a M Coupe?

Is the new KW set-up much stiff than the tck?
