Nitron NTR Track v Intrax iK2

[flipm3]

Beautiful setup.

I am in the middle of trying to decide which suspension I want to go with for this coming track season as well.

I apologize if this has been brought up many times in the past.

Are there any risks in using a full rear coilover? Did you do anything to reinforce the rear shock tower?

Thanks!

yes, I think it is widely known that the rear coilovers can crack the rear turret.

I have always used the Z3 reinforcement plates and also a solid rear strutt brace both to try to stop the turret from flexing with the movement of the damper.

Does the strut brace bolt to the fixing studs on the shock/turret, Where can I get one from, do you have any details.

Here are mine, but there are others.

The road ride is superb once adjusted to suit. No noise, no crashing, and my car is reasonably low.

On track at Donington I set up the car stiffer then road it left the rebound the same. Initially the car felt very good with great front end grip, braking was spot on (although I had my vibration from the ballpoint to cope with). The rear felt good as well so I decided with my limited track time to do some adjustment.

I turned up the compression damping (remote reservoirs) by 4 clicks (out of 16) so from 12 on road to 8 on track they were now on 4) in retrospect these were quite severe changes and straight away I noticed with Jim the car step out at CRANERS as we turned in left. It was trying to send the rear to the right. Now it might have meant we needed to up the rebound or decrease the compression but as only one session left I set it back to a softer compression and all was ok.

The adjustment is easy and exact. The affect of the adjustment seems unite pronounced so now I will try it on the road with minor adjustment to get her dished in nd wait for a Silverstone or maybe fit in a Snetterton in March.

Snett 300, would be a good comparison with the Intrax, certainly with the time you done last March

Great update! I recently inquired with a US Vendor for Nitron about different setups for the E46 M3.

What are your current ride heights from the center of the wheel to fender?

Alignment specs?

Thanks!

Hehe...please help a brother out! You're my only hope. No one in the States wants to give Nitron a chance, haha....

Just driven down to Simpsons and the Nitrons are just superb on road. I stopped half way down and just tweaked the rear to see what difference it made (2 clicks more on compression and then 2 more on rebound 25 miles later and you can really feel the changes take effect.

New Pilot Super Sport also have now got some grip so back end feels planted on the A roads down to Lydney.
