Never think of lower any of my cars before until I got my RCF last week. Just dont know which brand, how many inch and comfortable should i go for it? Please give me some advise. Thanks
There are two 'main' brand ones, if you're going to continue with just the spring, and they are "Swift" and "RSR"
My research, hope its correct, is:
1. Swift - Achieves a level stance, enough drop on the front (and less on the rear) to level car out. Also gives it a slightly tighter feel.
2. RSR - Achieves the lower drop, front and rear, but I think still level... just lower than Swift and the ride quality stiffness will still be similar to OEM. I'm not sure if this is right though, lower drop yet spring rates will feel the same just makes me shake my head, but there are a lot of threads and they tend to blend into each other after a while and conflict each other.
I am not lowered yet, will be, but I personally will be going with the Swift because the drop is not as much as the RSR but I'm more interested in the leveling look.
RSR are garbage. I believe they are softer than OEM as I have seen a lot of cases of people with RCFs blowing their shocks (leaking shocks) on RSR. Swift seem to be better as their spring rates are higher than RSR and people in gerenal don't seem to have much issues with them.
Thanks for the detailed update on Swift Springs, my reasoning is to help eliminate the reversed rake look (where the front looks higher than rear) but if the Swift lowered the front and rear almost equally I guess the rake is still there?
Meraki - As a seller of both products, can you confirm which company offer a better quality product? when I see a post like that of 05RollaXSR, going with RS-R does worry me....and he is not the one I have seen posting negative comments about RS-R. I am not concerned as to which one offers the better drop, but is it true that RS-R have caused many secondary issues?

Thanks in advance
I am stating based on cases in real life. I have seen at least 5 RCF owners blowing their shocks with RS-R springs. I compared the spring rates of RS-R and swift. Swift indeed has much higher spring rates than RS-R, which makes perfect sense as to why RS-R cause the shocks to give out. The engineering logic behind is, the shocks/struts have to work extra hard to compensate for the compression of softer springs because the main job of shocks is to control the movement of the springs when forces from all the different directions make the spring bounce up and down. The shocks bring the fluidity, smoothness and control to how fast and hard they compress and decompress. Usually, aggressive drops without coil overs come at the expense of spring rates.
Luckily, I learned my lesson on the much cheaper Corolla XRS when I blew 3 of my shocks in 2011 with the garbage Tein S-Techs that gave a 2.25 inch drop. I put koni yellow adjustables and got much stiffer Megan racing springs that had only a 1 inch drop and never had any issues.
Ultimately, it is really your decision to make, but definitely there is a trade-off there.

Sadly for me, I have an RC350 AWD and they don't make any for my vehicle....I guess I either out of luck.
1. Get the RS-R and risk it
2. Get coilover
3. Leave stock and suck it up
4. Ditch the RC350 and get something else
I see. I am not sure how the stock spring rates on the RC350 AWD compare to the RS-R spec'ed for your car. It also will tell you how the handling dynamics will change for the car. You might have to do some research. Maybe, Josh at Meraki can give you a comparison of the spring rates of OEM RC350 AWD with the RS-R. I am not sure how much do OEM shocks cost for the RC350 or RC300, but you might want to see If it does not cost a few grand like does for the RCF then it probably might be worth the risk maybe?
Anyway, here is one thread for you to read where the owner of this RCF warned people on the forum about RS-R. I guess, it might help answering any other questions you might have.
