My wish is to develop this FRS/BRZ in ways that will add more pleasure to your long term ownership, and hopefully to see this more like a long-term relationship with the car, like the AE86 has been and still is after 27 years...

And to keep people in the loop at the most detailed of knowledge, so as to understand the beauty that is designed into the FRS/BRZ/86 well beyond the surface, specs, and simple, current trends.

The Passion, CE Tada was speaking of, is not shallow at all, and it goes deep into the 6 years of his team's hard work at Subaru and Toyota.

You're doing a good service to the forum. I would like to know how you chose RS*R and how did they help you during the process for such a setup? I'm not very familiar with RS*R but I've heard good things.

Do they include shock dynos to prove that the dampers are matched? What spring rates did you go with?

Thanks for the tidbits Moto-P. It's good to hear the RS*R dampers ride better on rough surfaces than stock despite firmer spring rates. This implies a more digressive damper versus stock, which is always good IMO.

Did RS*R spec the damper such that it retains all the factory suspension stroke? Also, is that stroke positioned differently from stock? [i.e. will the car ride lower, have more or less droop and/or compression travel?]

What is the MSRP of the coilover set you have?

Thanks,
Ryan

Love it! Thank you for sharing Moto-san!

Those look awesome and very high quality!

RS*R chose us a long time ago to test suspensions on AE86's and other cars, way back in 2000, and also contracted us for operation and planning of RSR Drift Festival with Orido "MAX" Manabu and his Supra/S15.

So it was only natural, after knowing how good the RSR suspension was (and how expensive) to return to them for my S13 Drift Instructor car, my LS430 sedan project, and now this FRS.

RSR Sports-i has a recommended range of height from about 15mm to 35mm below stock, and the stroke range is optimum within these parameters. It does have plenty of stroke, despite the lower height as the coil case is double tapped both at the spring perch and the lower mount, so that the piston and shell can always be at optimum range at any preset height within the specs.

The MSRP for the FRS depends on options of internal valving changes or other custom orders. Mine is base setup, tuned by RSR by thier engineers to thier idea of what I might like (which so far has been exemplary).

In Japan, this set is Y207,700, which by today's rate is $2587 + freight. USA prices have not been set yet for this FRS application but likely lower. You can call RSR USA to find out more about custom options, exact prices, and shipping needs.

They can provide the damper rate sheets from tests if you need them, but does not come with this in the instruction set. They are QC'ed carefully however, and I have not had one unbalanced or malfunction yet, with only service being hairline cracks in the rubber top bushings after 15,000 miles on my LS430 set, that was easily replaceable.

My FRS set is set up with the 6kg/mm F and 7kg/mm rear, standard spec valve, and range adjustments, with rubber bushings rather than ball joints at the top.

Thanks for the info

I really enjoyed reading your review. Thank you!

Also, what is the est. MSRP for these for the USDM folks?

I love that you went with a semi-streetable setup (rubber bushings, soft springs, etc). Interesting that HKS chose to go with 8k rear and 6k fronts as well.

Another question. When Tada-san said the optimal drop should be -20mm/-15mm did he tell you any other reason except that it was optimal for suspension geometry?

Thank Very much Moto for this. RS-R USA has been one of favorite companies for aftermarket performance products for a long time and im very glad to see this product will be available for the FR-S. They make top touch quality product and i highly recommend them to every one.

I never had the intention on buying a coilover setup for my FR-S but after seeing this im very interested and will be on my list of things for this car now.

Iv had the RS-R down springs on my Integra now for 3 years and they have been amazing. I also have the Exmag exhaust on the car as well and its by far my favorite sounding exhaust on the market. So i ma little sad to see no exhausts will be out for the FR-S.

Couple quick questions. Sorry in advance if I missed some of these details in the write up.

1. Do these have independant compression and rebound adjustments? Or are they single adjustables?
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

Nice writeup and suspension, is your wheel selection going to be HRE? If so do you know what specification they will be giving you or whatever wheel company you decided to use?
