Deciding on coilovers and springs
 

Anyone have any experience with Silvers Neomax coilovers on a frs or brz? I was trying to decide between Fortune Auto and RSR and saw someone on another forum say Silvers is Fortune Autos supplier. Tried to find a review of them for our cars, but came up empty. Also trying to decide if swifts would be worth it just for daily driving. And please dont recommend ST of some V3s. Looking for coilovers that adjust by a rotating bottom bracket.

What are you doing with the car? Street car hitting back roads, track car, autoX?

Daily driving. Occasionally some spirited backwoods corners with some friends. But I dont really give it hell. Most of the corners you cant see around and they are thin roads.

I'd just go with RCE yellows with B6's. Retain the stock top hats and get some camber bolts.

Id like to drop somewhere around 2-3 inches. So I want to go with actual coilovers. I want something that I can rebuild so they last a while. Thats why I was looking at the fortune auto, rsr, and silvers. Any experience with these or something comparable?

At 2-3 inches of drop you are going to have very little bump travel and any coilover is going to ride terribly. I'd just go with cheap if you are looking to go that low.

Don’t the STs adjust with a rotating bottom bracket? But just one instead of two.

All the coils you mentioned I believe are manufactured by Bor Chun (BC Racing) but rebranded and slightly modified. They are not bad on a smooth track, but you may find them lacking in the street comfort category. Basically the high speed damping is pretty good but the low speed damping can be brutal.

I would personally look at Tein flex Z/A/CSG A, or if you end up being OK with ST’s, RCE and Greddy both have tuned variants for the 86.

But as @NoHaveMSG said, you may be best off getting a sport shock like the Bilstein B6 which is honestly pretty firm (in a good way) and will last you longer than the struts/shocks of all the aforementioned coilovers. Plus you can choose whichever spring you want to go with it. If you really do want to drop 2-3” I would choose the Bilstein b8 to keep a short lowering spring fully captive at all times.

Not a lot of coilovers are engineered for a 2-3" drop (due to the negative consequences mentioned above), but you're already looking at some of the few brands that do. So if you're dead set on going that low...

The RS-R Black-i have had favourable reviews on this platform (not to be confused with their Sports-i model, which is the more performance-oriented/moderate lowering model). And rather than typical pillowball top mounts, they use urethane bushings in their top mounts, so they probably have less NVH than the others. They're made in Japan, always had a good reputation, and been around since the 1980's.

Some reviews on this platform:

The Fortune Auto SuperLow Spec comes with Swift springs as standard...unless you're looking at the regular 500 Series. The 500 Series they may not achieve the 2-3" drop you're looking for (I've read they don't go very low on this platform). However, the SuperLow Spec seems to be new, haven't seen any reviews about them...


I briefly researched Silvers Neomax in the past and also didn't find any reviews for this platform. Only found reviews on other platforms and that they're made in Taiwan (probably by BC Racing as mentioned above). I also recall reading somewhere that they are a supplier for Fortune Auto.

Due to the lack of experience/reviews of Silvers Neomax on this platform, you might be the guinea pig too if you go this route. And worth contacting them to see if their standard kit can even lower this platform 2-3". And their site doesn't mention what the "Super Low Kit" option entails, so probably worth asking about that too.

Whether Swift springs are worth the upgrade are subjective on a car that doesn't see a track/hard driving...maybe if you're keeping the car/coilovers long-term? They've got a reputation for maintaining consistent spring rates and performance (reaction speeds and travel).

This is exactly the kind of response I was wanting! Ive read the post about ruining the car a while back and have a couple of comments and questions about some things said. Will update soon. Thank you so much.

Just to add something not mentioned above is that when you go lower than 1", you also run the risk of damaging your CV joints (rear Axles) in the long run.

So going that low is not recommended.

A friend runs silvers with a 255 squared RS4 setup.

Car feels great on the road, though he is maybe lowered 1 1/2 inches, 2 max.

Without a diff riser kit to fix the axle angle? :)

Is there one good for not adding a ton of nvh?

Beats me LOL. I'm lowered 1.5 inches on tein flex z's and between the verus aggressive diffuser and my front lip, I'm constantly scraping every driveway and misshapen parking lot I enter :bellyroll:

The axle angles on my car didn't really change all that much. There are some pretty bad pictures around here for people who've dropped so the tires are tucked behind the body lines and I don't know how they drive around without losing bumpers and smashing the frame rails.

I think I’m going to do 2 inches max after measuring. Going to get whiteline lower control arms to fix the camber and hopefully my axles wont be too bad.

I'm not sure if the whitelines come with anything extra special but I got the SPCs and they look identical but in black. I read somewhere that the Moog ones they have on RockAuto are also identical for even less. Camber will do good things in the rear but toe will need to be addressed. You should have enough room in adjustment to most likely be okay.

Thank you!

Deciding on coilovers and springs
 

Got messaged about a set of used RSR sports with 8k miles on them. Im thinking about moving on them, but idk if buying used on this is a good idea or not. The adjustment range on them would keep me out of trouble with breaking stuff lmao. What would a decent price to get them for be?

Sent you a private message.

I'm missing a lot of inner fender liner in the front :D

Imo buy new. All springs age and warp differently. Buddy's driveway could be sloped or the parking spot isnt even. Depends on your goals, I suggest to focus more on the weight of the spring. 8k springs like bc racing brs or hks hipermax sp is meant for track and it starts to get really brutal for daily. Took me a while to get over how stiff the car rode after. If youre just chasing fitment and dont really care about performance tein flex z are good budget option with lots of adjustment. Get ready to spend hella dough on LCAs and other fitment related mods. Fortune500 are solid too.

Here come the bump stops. Know a guy who ran autox, track and commuted his. He kept the OEM suspension specs within millimeters for height even though he ran coils and many more mods to provide wider camber adjustment range.

He turbo'd it to 275whp and bought wider wheels and larger diameter tires. It looked lowered as it took care of the wheel well gap look. He had to retard timing in first and second to keep from breaking loose too easily with good summer tires like the Advan AOD8s I bought from him in stock sizes.

Just sharing why I'll stick with near stock height. I'd lower an inch myself for a try, that's about it. As low as OP started thinking, that seems like airbag zone to me.

Sorry to necropost, is it possible to calculate the variation of scrub radius according to the camber?
