I will send a email tomorrow to Cortex! I was watching my latest video at our local track and the car is now much faster then a year ago (all the goodies added and slowly improving driver....), but noticed in the video that the front is bouncing off the springs much more then when I just added the P springs. Really noticeable. https://www.youtube.com/watch?v=Nci6BTizlsw

I almost got to the times of the stock GTRs of a years ago... But now the GTRs are with 800hp and Hoosiers so the heck with that. Lucky for me they moved up a class.

I had some braking problems (me, not the car) and my O2 sensors where giving me codes but I got 48.62 and I really want to get to 46.xx one day. Hoping that the coil overs can help it happen!

Any comments are very welcome!! Mean/friendly, what ever is fine as long as its helpful!

PS. the missed shifts were the clutch sticking to the floor still

Thanks. More or less convinced! Just waiting to see if its worth it to go by stages...First front coil overs, then rears and finally the watts linkage. Have a new frpp lca and bracket waiting to replace my bmr set.

Must say a little disappointed that the Cortex koni setup has the rears difficult to adjust. Looking at the very nice COrtex JRI setup but that goes into the +4000 bucks range. Was looking as well at the http://www.americanmuscle.com/hr-club-coilover-1112.html#fitment H&R club sport set up or the Eibach R2 with much stiffer springs some thing like 450/250.

All these options!!

I'm using the Cortex Koni DA front and Penske DA rear setup on my car and in terms of adjustability both ends of the car are fairly easy to adjust without removing the wheels. The Penske's in the rear can be adjusted by simply taking a scissor jack and raising the body at the ass end just enough to reach your meat hooks into the wheel well enough to turn the dials up top for compression. Rebound can be done without jacking at all if your arms are long enough otherwise a set of race ramps will do the trick.

The Konis up front can be done by cranking the wheel fully in one direction or the other for compression and rebound is done at the top.

I'm not going to lie, having two different brands of dampers on the front and rear definitely takes a bit more effort to dial in but it is doable and works well if your willing to put in the time required to get them were they need to be to work in harmony.
