K thanks

I have the poly transmission mount and z1 solid aluminum motor mounts and there is little to no vibration increase which bothers some, but you have a race car lol. You will notice an increase in noise because the suspension becomes more ridged. You will also notice an immediate increase in acceleration as there is no engine twist.

I noticed on the first cold startup was how ridiculous it sounded inside the cabin. There was a ton more vibration at idle. I'm editing this weekends footage now, but footage won't show you what it's like to drive with them.

I think the vibration is mitigated by the 4 point roll bar as it significantly stabilizes the car.

The differential was predictable and I felt a level of control over the car I didn't think was possible. Instant power delivery, facilitated throttle steering, consistent power delivery over the hairiest of bumps/uneven asphalt, and it felt like it kept me going straight in threshold braking (occasionally it felt like the rear wanted to step out, but the slightest of counter-steering settled everything instantly). The cusco 1.5 way RS is a good choice if you're looking for a differential for track use

YMMV, but my setup includes: bridgestone RE-11's 265f and 305r, powertrix coils, solid engine mounts/urethane transmission mounts/ SPL solid diff bushings, and some aero modifications.

Didn't stop by to say hi, but you and mike looked pretty good out there. Had a big off in the 3rd TT session on Sunday and packed up to head home. Saw this pic, not sure if you had. Fwiw, my guess is you are very near or on the rear bump stops....

Would the OS Giken be loud on the street ? Do they make a 1.5 and a 2 ? Which one would be best for me ?

No, it is near silent and call/talk to them. They will get your sorted.

Thank you! You should have stopped by! We had a ton of down time.

I hope you and the car are okay.

Long story short, I need to have the rear suspension raised and re-aligned, I just don't have time to get the car to a shop to take care of it.

Not cool. I have had something similar but with no brakes at all. It officially became my nightmare dream from that day forward....LOL

I am pretty sure they're 13k front and 11k rear.
