2. Will RSR share with you who manufactures their valving? I would be suprised if they make their own considering the volume of dampers they produce. I'm only asking to see if it is a known reputable company.
3. I assume these are aluminum bodied dampers. Did you happen to wiegh them compared to the stock units?
4. Did you change your alignment specs from stock to this? I'd be suprised that steering input would change because of the shock a noticable amount without toe changes.
Are you in SoCal? My car arrives in the next couple weeks. I'd be curious to see how the RSR damper performs on track to other offerings.
Best,
Matt Andrews

Just how much depends on stage and road racing conditions, and again, driver skills to actually put that to use effectively.
As for me, I had my car corner- weighted at each end with me in the car, precisely to center the contact patch between left and right. I didn't worry too much about fore/aft adjustments, as that is more inherently dependent on what type of racing, venue, and tires/brakes and adhesion and it can vary greatly, so I just left the overall balance alone from stock, and accepted the change slightly, just to personalize the looks of the car (height fore/aft) as more a priority (Yes I like my fast cars, looking good too, but functional. )

2. RS-R manufactures and designs the case, piston, valves and all hardware components in-house, and I've visited the manufacturing facilities near Osaka, Japan, so I trust them that much.
3. These are aircraft grade aluminum shell cases and ends, (I forgot that the actual T rating of the alloy). For the FRS set, the suspension coil and shock assembly with mounts, weighed 3lbs less than OEM parts removed to replace (total of all four ends). While the OEM's weight is mainly in the large coil springs, the majority of weight on the RSR Sports-i is in the case shell and valve/piston which seems much more strong than OE internals and shell case.
4. Due to the very long lower arms and steering rack pivots as well as toe-locator rods, the FRS needed minimal correction of 0.4 mm at both ends of the rack-ends, to bring the toe back to where it was originally with OE height, this, at 32mm drop. I'd need to re-check after a few dozen miles to see if any settling of bushings or springs caused any changes, but that's what I see at this time, 1 day after installation.
Yes, I am in Los Angeles/South Bay area and hope to meet you soon for a cup of coffee or snacks~!

This is good Stuff...as my own build with my BRZ will become reality here soon.
Matt Andrews..thanks for the intelligent questions. You seem to have similar goals in mind with this platform that I do.
Moto... you insight is phenomenal and respected. Thank you..
I have a couple of questions also:
-What type of competition are you going to participate in?
I will be building my BRZ to SCCA Solo spec in whatever Street Tire Class it falls in.. as I have already started to accumulate the needed parts, rims/tires etc to facilitate this..
-Moto, is it wise to say going with a stiffer rear, even tho slightly, makes it more neutral??? Since it is a new platform, Spring Rates were a crapshoot. I was going to start with 8k/8k.. but that sounds to stiff?? now.
-With 35mm maximum drop, would Steering Compensators ie: Bump steer kits/Ball joints be a wise investment?
-Will you still be using the stock swaybars? or are you planning a upgrade there?
-Care to share your Corner weight info???
-If you were to run camber, How much would you run, Do you have any idea of the how much Static Camber you have during aggressive driving?? And do you know if Toyota or Subaru is going to offer 'crash Bolts' to be able to get more camber out of the stock mounting???
- how much room do you have between the shockbody/spring and the inside of the tire at this point??
Thanks sooo much for your time..The information you are providing will go a long way in my own build. Much appreciated
