I'm not too proud to admit that I am that guy. Sounds like these may be the ones.

My kwv3 were actually less shipped than msrp on those, but I did luck out with a holiday coupon on a site that was already discounting them, and it did take searching.

But still, it seems like the street price on kw is a good bit less than most think. I'd send some pms around here and maybe with some vendors on nasioc.


Put on the v3 last night, first time i've actually improved the ride of a car ****ing around with suspension.

I'd like your input helping me compare the new Speed By Design Pro Street coilover to another in the same category (I think), the RaceComp Tarmac 0.

They both seem to be tailored to the spirited street car that sees the track several times per year.

I like that the SBD Pro Streets come with camber plates unlike the Tarmac's, but I don't know much else about them and how the technical specs of each compare, and how they contrast to the next tier up like the RCE Tarmac II and Tein SRC.

There are 100s of "spirited street car coilovers" nowadays. Seems a lot of them are cheaply developed with little, to no, real world nor extensive performance/track r&d and appear to be more for show. I'm unsure about SBD, if they could be one of those "cheapy coilover companies"...but I can say I have never heard of them. Of course it's hard to market a new company and product, even if they could be an awesome company/product; but we would need info, reviews and or news to find out if they are worth it. There's just so many new companies releasing cheap coilovers made in africa/china/etc. these days; that it's always safer and a better bet to go with a reputable company. All I know, as of today, is that RCE is definitely NOT one of those cheapy coilover companies - RCE is race proven and the realness. If it were my money, I would go RCE.

i trust guys like RCE because they are down at the ground level talking about what it is that they do, which is take existing hardware and modifying it to suit their needs, and they are open about whose hardware they are using and how they are modifying it.

same for the guys making the RS-i units

they go out of their way to explain with very specific detail what sort driver their product is aimed at and how exactly they are matching their product to the activity.

any time i read ads where it's all just fluff words (i mean, who would ever say "our product provides a harsh ride") without any real meat between the lines makes me cautious.

How would I go about selecting a good starting spring rate that doesn't end up with my tires being driven into the front fenders? My plan is to lower the car approximately .5 inch.

Our coilovers come with 400 lbs/in front and rear rates which may work for you. You might like going a little firmer.

What is the usage of the car? Auto-x, track, DD?

It seemed like the SBD coilovers were much more heavily intended for the street. The shock dyno they posted looks pretty soft, so that makes sense.

I don't have first hand experience with them, but it seems like they focused much on the street while our RCE Tarmac series.

Tarmac 0 is almost a Tarmac 2 with the damping preset at a certain setting with softer spring rates.

T2 gives you a lot more flexibility in both directions (sport and comfort) available with the 2 way adjustability.

Need a recommendation for coilovers. Priorities
1: above all, needs to pass the wife test
2: I lovey auto crossing, trying to go twice a month, but only close nationals if any, so say local only
3: do not want to get on hands and knees to adjust(?)maybe ok
4: willing to go high end, still in CS, but will end up in STX

Given the above priorities what would you all suggest.
I have researched pretty heavily but am in need of some real world experiences.
Thanks in advance for any input.

Auto-X and DD.

What does using the square rates do to the balance of the car?

Depending on your budget....

Although the adjustment is on the bottom up front, it's worth considering Ohlins for you. You won't be adjusting them often. Myles in the office had them back to back with our own RCE/KW Tarmac 2s and can give detailed impressions on both. Ohlins will definitely pass the wife test.

Our T2s are excellent as well and offer a lot of adjustment, which may or may not be what you're looking for. A little more aggressive than Ohlins but still very wife friendly IMO.

Beyond that price range, JRZ or possibly CSG's Tein SRC coilovers could meet your needs but both are a little more track oriented. Still streetable for sure and can offer excellent valving.

With the proper set-up, IMO it makes the car very easy to drive fast with the ability to get on the throttle with confidence.

It's especially good for auto-x...the extra front spring rate helps with quick transitions while keeping the rear end "tamed." These cars do not need much help rotating.

I think you could go with 9k/9k. It will be firm on the street but very DD friendly. Excellent for auto-x.

Are there any shock dynos of your T0s vs T2s...

and also dynos of Monoflexes, SRCs, Ohlins R&Ts?

And dynos of the cheaper setups: B8 (once someone has them) vs T0s vs B14s?

Truthfully? It just seems like "another option" to me. I haven't seen anything posted by SPD that says otherwise. He politically declined my offered to give an unbiased review.

A single shock dyno doesn't really say much..

1. lower spring rates, but well damped, is what you're looking for. The well damped part is the expensive part, but you 100% get what you pay for in this department.

2. Any well damped coilover will perform well, in addition to providing a good ride.

3. Have you considered spending a bit extra to get remote damper adjustments? For example, Tein SRCs are offered with an optional EDFC (electronic damper force control) that allow you to change settings on the fly by pushing a button on a control unit. There's also active EDFC, which can change the dampers for you on the fly, using predetermined parameters (speed, lateral G, etc.) that you can program to suit your needs. The EDFC is compatible with all Tein dampers, and most non-Teins are compatible as well. It uses a stepper motor, and just needs to be attached to the damper adjustment. Otherwise, you'll need to be on your knees or sit/lie down on the ground to get to the bottom adjustments of most damper setups.

4. JRZ with lower spring rates would be my recommendation if you're willing to spend the big bucks on a high end street damper.
