i've been lookinf into coilovers and need some help. hks are expensive. tein are reasonable. is it worth the price difference? i've also heard of people who don't like them. so if i don't go with coilovers, what shox and springs would recomend? money is not that much of a problem. thanx. fist poll posted so hopefully it's right.

I voted for the tein's. Now I voted that because they are a solid coilover that will allow you to hit the track and also have a pretty smooth ride on the street. The Flex are a good compromise between a race coilover and a good road one.

i put a vote for JIC Majic FLT-A2 coil overs, i have had them for a while now and are fantastic for the track and street.

thanks so far. ive also been lookin at the ksport.

I vote for revlaved Koni yellows in Ground control strut tubes, ground control tubes, with 2.5" springs, 400 front, 275 lbs rear.



But that option isn't available

Coilovers arent great for a mainly street driven car IMO. I have driven a couple different rides and if you are building a track car then ya, coilovers are the way to go, but if you want a comfortable street car springs and shocks every time.

i vote for the same option as Cheers did. I run GC's with eibach springs over koni yellows on my monster.

thanks guys. the car is not my daily driver and i want to put on the best performance suspension(with out getting out of control).should be pushin close to 300 to the wheels when my car gets back in a couple days. how will the car ride different with coilovers opposed to whith that setup ^.thanx again.

High dollar coils overs are WAY overrated IMO. Most people don;t have the equipment or the know how to adjust CO's for anything but ride height anyway.



btw, my car is track only with estimated 600 rwhp weighing 2200lbs.

When the first thing I would look for in a coilover is how well the dampener is designed. Will the dampener fade after a couple laps? Remember the dampener/shock has oil inside that gets pushed in and out valves it heats up. Eventualy it will fade in the same sense brakes fade on the track when they are too hot. When a dampener fades it will no longer be able to dampen it.



THe next thing you look for is the coilover's dampener ability to control rebound dampening. Hard to figure out unless you can see shock dyno graphs. Partly why I believe in the ground control setup, they have been supplying rx7s since the IMSA days, so they have the rebound dampening rates somewhat figured out. Those new taiwanese or phillipean coilovers guys probably don't know, or have any experience racing rx7s on track.



Rebound dampening controls the car's dynamic response (ie handling) compressiong dampening only really controls ride comfort. To design a dampener that has lots of rebound dampening is difficult to do.



I vote for Koni Yellows revlaved by ground control mounted in ground control strut tubes, ground control sleeves, and ebiach 2.5" springs. They also have a rear pillowball mount. If i were to redo it I would go with that setup. I decided to save 400 bucks and went with ISCracing's bilstein setup. Sucks. Build quality is low and htere isn't enough rebound dampening. It works ok though. But the groudn control setup is overall better.



If you feel that ground control still isn't good enough, you can go with:

Penske

Ohlins

Multimatic

Or perhaps you can talk to Bilstein into revalving a set of their "HD" rx7 dampeners for race purposes, but you loose the adjustability option.



Further coilovers that claim they have 30 or 40 clicks of adjustbility are BS. Since when are you going to be able to tell the difference between the 24th and 25th click? The only way you could if you were datalogging the suspension to see the wheel rates. Even then I'm willing to bet those low end japanese/taiwanese/phillipino coilovers won't show any difference in the graph/trace between the 24th and 25th click.



that is my opinion.

I voted "no coilover".



Eibach pro, with Illumina, or KYB. You didnt mention any track events, so im assuming this is a street car.



If your looking for bling to show off, go with tein.

thanx guys. very helpful posts. i'll let u know what i go with and how they perform. should be ready whithin the next month.

I have built my track car with input from the RX7 road racers around the Seattle area, that I trust ,and I decided on....

Ground Control plates with eibachs springs, the Tockico Illuminas had to have the tops machined to fit the upper plate correctly, (buh by warranty), and I have the pillow ball bushing. (pain in the A$s job, might as well replace the bearing while it's apart.)

My local guys have reset the alignment and marked the track camber and toe and the street setting so I can switch it reletivly easily. The springs,/height were done with 4 scales. I am picking it up tonight now that the cage is finished.



I am looking forward to seeing how it does now that it is set better than my initial Scientific Wild Ass Guess! (SWAG) I can say that you have to want the maximum handling advantage bad as is is a STIFF ride, and here in the Seattle area we have potholes you can see by Satelite! https://www.nopistons.com/forums/pub...IR#>/blink.png

This is my daily driver and there is a price to be paid! Best of luck with yours, I know I'll like mine first time I take that Z car on turn 8 at Pacific Raceways!! https://www.nopistons.com/forums/pub...1047683473.gif

i have tein personaly i love umm

Tony at awrracing.com makes a nice complete suspension package for the 2nd gen with coilovers and hard mounts and a rear camber adjustment.

WOW, it is worth the stiffness for me! Did my first track day at Bremerton and was consistantly 65-70 in the slaloms on street tires. (old Kuhmo esctas or sumpin) I had the struts at 3 for my initial testing and won't mess with it till I have the race tires, spacers and negative front track camber on, but I am happy happy! https://www.nopistons.com/forums/pub...1047683329.gif Lookin forward to what it does in a race setup! https://www.nopistons.com/forums/pub...DIR#>/cool.png



Next time I have to slog it to Portland I might whine, https://www.nopistons.com/forums/pub...O_DIR#>/11.gif but all is forgiven when the track time comes! https://www.nopistons.com/forums/pub...#>/BURNOUT.gif

by the way,

Jeff Clark in Puyallup is the one who advised that I try this set up!

Thanks Jeff, see ya this weekend at Pac Rcway.

my experience with tein has been nothing short of a nightmare, 3 seperate cars had failures

That's weird. I've got the ground controls on Illumina's and I didn't have to modify the strut to make the stock mounts work, but I didn't go with the pillow ball, either. I went 440 in the front and 300 in the back, and it's solid on the road. More solid than I am in the driver's seat. I went over a crest in the road and whacked my head a good one against the ceiling https://www.nopistons.com/forums/pub...#>/biggrin.png Time to tighten the harness

Yeah I had a nasty bump near here where there is monster road repair going on, and I am glad I was strapped in tight, but I think I shrunk 1/2 an inch on launching and landing.... Bad news is, with the concrete guys on strike, makes me wonder when that awful stretch of I-5 will be finished... I try to avoid it at all costs! https://www.nopistons.com/forums/pub...1047683358.gif

get real coil overs not GC and struts.



Silkroad RM8, or JIC FLTa2

I just got some used jic flta2s. I havent dailed them in at all. **** i dont eve have an alignment, but the car really handles. nice and flat. feels like a different car compared to my old tociko blues with some intrax springs. cant wait to get some new bushings and some tower bars
