Coilover System
 

Hi all,

I'm currently looking in purchasing a coilover set for my current FD. What brands have you guys have found have liked/worked the best. I'm all about the quality, but again do not want to spend crazy $$$ unless needed. Let me know your thoughts guys, have read that a lot of people used the ground control setups, or even the eibach pro systems. This is a street driven rx7, but may partake in some track days with the car.

Thanks,
Robert

For a street driven RX-7 that sees only a few track days, I recommend a spring/strut system instead of coilovers. Look into Koni Yellows with Eibach springs.

I really like my Ohlins coilovers. My car is street and track driven.
The Ohlins ride better than my Koni Yellows with sport springs, and handle better on the autocross too. But, they cost more.

For a street car I like the spring rates in the 7-9KG front range and 5-8KG rear range. if you do high speed driving over bumpier roads an ohlins coilover shock is good as it blows off pressure to get the wheels back on the ground quick. if you don't do high speed driving on bumpy roads the linear valving works just fine and you can take your pick from most lower shelf coilovers. the Tein flex Z looks to have good rates and looks good on the shock dyno, they are not rebuildable but you can replace them, and are extremely affordable. they are a twin tube design and not a monotube.

ohlins are good coilovers but very expensive, i personally love fortune auto or stance coilovers, they can be found for around 1000-1100 shipped and when ordering new they can be ordered in your desired spring rate.

i think its cheaper to buy coils then buying konis then shocks etc...buy coils once and be done.

Bilstein b6 or b8 are a great bang for the buck, although I haven't tried them in an FD. They are a monotube design unlike the twin tube koni, and have a nice digressive valving curve. Koni's tend to be extremely rebound biased and make the car jack down into the bumpstops. It makes the wheel feel responsive, but sacrifices overall grip in my experience.

I have heard the Bilsteins ride very rough, as in so rough that people removed them from the car because of the initial roughness of them.

I revalve bilsteins at my day job and have tried them on many different platforms. I've found them to always ride reasonably even out of the box, so it's odd to me that this is how they are known in the FD community. I'd read that as well. Sometimes on the forum one guy that has influence tries something, reports his opinion and it becomes gospel. Everyone will have different tolerance for ride but i suppose it is possible that they messed up on the valving formula.

I agree with you. I always wanted to ride in a Bilstein valved car. they are monotube design and the shock dyno looks good for a good handling acceptable ride quality ride. The car wasn't an FD, it was another car.

BC Coilovers has there BR system and now DR witch im using on my 93 and they feel amazing and not to expensive.

By the way im selling a set of Tein Coilovers in perfect condition.
