Another JRZ RS1 upgrade

Decided to upgrade our AW E92's GC EDC setup and go with something a little more serious.
This particular car hasn't really seen any track duty yet, but we'll start with the occasional day here and there beginning with an event at Laguna Seca on the 8th of next month. However, we really plan on keeping it a street car for the most part.

We'd been looking into the JRZ RS1's already, but were considering a few other options as well. After reading through one of Stalker's threads I decided to give Bimmerworld a call. The crew at BW has always been helpful to us in the past and with their added experience it was a good place to get the detailed answers I needed.

Anyway, after a few conversations between Bryan, James and myself, along with conflicting schedules and race weekends, we finally decided on a setup that we felt would suit our particular, and slightly challenging, needs with this vehicle.

We'll be reusing a few components from the current GC kit and there are still a few items on the way, but this is what arrived today.



We look forward to getting these on the car and will follow up with with more details.

Thanks to the crew at Bimmerworld for great service and support once again.

Nice swap bud! Provide feedback with these on the car as compared to your prior setup.

You are going to love them.
What spring rates did you guys end up going with? Also very interested to get your feedback on the RD sways with the RS1s.

We went with 550 F, 800 R.
Still waiting for the RD bars to come in and GC is going to modify our existing camber plates to accommodate the new 2.25" ID springs. So a bit of down time on this for the next week or so.

Nice setup! From what I've learned from vendors and on this forum it sounds like this is an awesome SA damper - enough range to create a proper track setup yet still have the range to create a street setup that absorbs bumps/expansion joints even with track-biased spring rates

Yes, we finally got it installed after a few minor changes to the setup.
Because we're running this car lower than what's really "recommended", we had to change the front springs as well as run a bump stop in the front for insurance purposes.

Got it all corner weighted and aligned and then headed to Laguna Seca the next day. Unfortunately, we couldn't get the RD bars in time so we're not currently running them. May still go that route as I believe they will benefit this setup on track with these spring rates.
These springs feel a little light on track, but certainly enough for the street, which is where this car will be 80+% of the time.

The adjustability of the RS1's is amazing. You can go from darn near Cadillac ride to Cup car in a matter of turns. I may be exaggerating a tad, but the difference is dramatic... even with 550/800 springs.

I didn't push the car really hard on track, but towards the end of the day I picked up the pace and the car felt so well balanced. Ran the fronts at 15 clicks, rears at 17 and never felt the need to adjust.
Currently running 13 clicks front, 15 clicks rear on the street and the car feels firm yet compliant. These RS1's really do suck up the bumps well.

Overall we're very happy with this setup. It's very streetable yet leagues ahead of the old EDC setup. In all fairness to the GC EDC kit we had, we were simply out of travel due to how low the car was sitting (something I fear is the case with how most of the EDC kits out there are being used).

Many thanks to those that helped!
- once again to James and crew at Bimmerworld, who despite being on the road, continued to support our efforts
- also, a big thank you to GC for modifying our camber plates to accommodate the new 2.25" ID springs and turning them so quickly
- and to Tom at EAS for supplying the Macht Schnell EDC module

Here are a few pics, crappy iphone pics included, sorry.
You'll notice the corner weighting was done with our street wheel/tire setup instead of the track setup since this is how the car will be driven the vast majority of the time.

The SSR's are 18x9.5, 35mm offset, roughly 18.5 lbs each. Usually run them on our E46, but they work well on the E92 with 10mm spacers up front and 12mm spacers on the rear. Picked them up back in '06-'07. Don't think they're offered in 5x120mm anymore though.

The JRZ's have been holding up very well for street duty. The car is so much more capable and planted, even with the higher spring rates. I highly recommend these based on our experience so far.
We'll be tracking Infineon next week and look forward to seeing how it works there as well.
