Whats up guys, I've learned a lot about 13Bs and their supporting systems but now I'm getting into suspension tech as I am becoming more serious with tracking my car. I'm looking into coilovers and had originally planned on using Tein Flex's but I read in Sport Compact Car's Project RX-7 article that using a coilover with separate adjustments for compression and rebound can allow you to setup a very good street/track compromise that handles and rides well? So I found the Tein Super Race coilovers, do these coilovers incorporate any race only features that wouldn't be desirable on a street car? My car is my daily driver (although I have my CBR as an inconvenient backup) and I'm going to try to track it maybe once a month but I want it to handle extremely well when I do. So what do you think, Flex or Super Race?

And on a side note does installing adjustable sway bars improve the handling a worthwhile amount? Also where would I get some as most sites just seem to sell larger or stronger bars and mounts.

 

Please do a search on coilovers. The true honest answer that nobody wants to hear is this:

*if you have to ask what coilover to get, you don't need them.

 

go with the Flex. amazing coilovers

 

I just think that with my car having over 300rwhp, the stock r1 suspension is going to be an issue on the track and I'll go for a fully adjustable system that will help now and I can make full use of later. I did a search for the super race coilovers and nobody seems to have experience with them? Is there a shop in the bay area that with dial in coilovers with corner scales?

 

I have the Flex on my FC and I love it. The best suspension I've owned. dont get me wrong, the ride is rough for street use but still very worth the money non the less.

 

Can you adjust it to be really soft also?

 

Yeah you can make it softer but its not like there is a HUGE difference between the hardest and softest. It really just make more of a difference in the performance of the suspension as it's going into the corner.

 

So even the softest setting is still fairly harsh? How would it compare to stock?

 

tein flex is the way to go.

 

You are wrong. Get some track time in with the stock suspension before going (a lot) stiffer. You will thank me later. Besides, unless you have a single turbo, you will not be running 300+ rwhp at the track, because you'll need to dial the twins back to 10-11 psi to avoid overheating.

Roger Krauss Racing in Castro Valley can take of you once you move into coilovers.

 

IMO, the suspension and the power are separate. IMO, it comes down more to the use of the car and the driver's ability. The stiffer you make the car, the less feedback you get from the car. For a driver with not a lot of seat time, this can be a bad thing as they might not recognize what the car is doing until its too late.

I would recommend tracking the car without coilovers for a while. A nice shock/spring combo will work just fine. When you find out you are able to outdrive that setup, then upgrade. By then, you'll have learned a lot and be able to pick a setup which will suit your needs by using your own experiences with the car.

I've been using Tokico shocks with the Tein S-Tech springs on the track. I would recommend Koni shocks for a few more bucks, but the Tokico's are definitely capable as long as the spring isn't too strong.

 

Ok, you guys convinced me Whats a good beginner Koni shock and spring combo? Should I get a lowering spring? Thanks

I tracked a Tokico/Eibach setup for a few years. The Eibach springs are a very good compromise between performance and comfort as well as making the car handling very predictable. Mating Eibach's with Koni's would give a similar and most likely better experience.

If you want something more aggressive, a Koni/RSR Race Spring combo would be another choice.

 

So these: http://www.rx7store.net/product_p/eibachfd.htm and these: http://www.rx7store.net/product_p/konifd.htm ? Should I lower it the max that the strut will allow? Thanks

-Andy

 

The Eibach's do lower the front more than the rear. Typically people run the rear on a lower perch than the front. I would start with the front on the HIGH perch and then the rear on the MIDDLE perch to see how that looks.

 

Ok, cool thanks. So can you say how much better it will handle and how much harsher the ride will be over my stock R1 suspension?

 

Unfortunately, those would be subjective answers. For me, it transformed the car. Here's an old conversation about the same topic:

Ah, great. So the car should be even easier for a beginner also. Hopefully I can get these on before my next trackday
