i have an s2k i love the handling however my s2k seems to not be worth its payment versus the problems it has given me. i love my turbo fc but i would like to make it outhandle the s2000. please look at my signature for my mods and tell me what you think i should do.. the only thing different i have thats not listed is mmr complete rear mounts, an fd torsen, and tein camber plates up front. spring rates are 400/325

I would say, new better shocks(maybe revalved to match your spring rates), and replace any bushings that haven't been changed yet.

What size are your rims? What brand, model, and size tire are you running?

s2000 handling = amazing. thats FD territory. i dont think FC handling will be better, per se, but you can take measures to maximize traction. you'll want all the susp goodies, to include full poly bushings, stiffer coilovers (dampers particularly- are agx's valved for 7k springs up front?), and an aggressive alignment. the mcpherson struts up front are a big drawback, so the car needs to be pretty stiff to really turn.
silk road, zeal, stance, tein, and JIC all make good coilovers.
for tires, you can squeeze 255 front and 275 rear with 20mm front fenders and rolled rears.

PS death to me lol

To start you'll want to upgrade to spherical bearings and heim joints on all suspension pivot points, to eliminate any binding issues. Next you'll need to correct the geometry in the front, by using roll center adjusters. Then you'll need adjustable lateral links plus the three camber links in the rear. After that you'll need real shocks, preferably mono-tube with a good amount of rebound adjustability. Compression is not as important, since that is the springs main job.

You will also want to reduce weight as much as possible; the effect of this modification is worth more than it's weight in gold; excuse the pun. But it really affects all aspects of the car. Acceleration, braking, handling.

Your alignment and the amount of front camber will also have to be carefully set.

Hope this helps a little bit...

i had been thinking about the spherical stuff. i noticed when i got the camber plates that the suspension when the car was lifted no longer binded up front. ive been thinking about getting new parallel bars for the subframe so i could adjust toe a lil better and some new strut mounts to get things a lil more loose.. i have also been thinking about chassis stiffening.. i drove an nsx this past weekend i know i will never get as good as the s2k or nsx but damn i think i can clean it up.. (add some spot welds and braces) i have been thinking about coilovers i really dont have alot of moeny for all this so i was thinking maybe buying the megan racing coil overs. i really dont want to buy an fd but things are starting to look like ill have to:-( I think FDs cost to much plus i kind of have to work with what i have. oh yeah by the way i cant change my signature i have tried. I am running 235-255 on the rear 9.5 inch ssr wheels . and 235 up front on 8.0 or 8.5 it slips my mind right now. i burn up tires fast so nothing stays on too long.

Yes but what tire brand and model are you running?

Tires are the most important mod you can do to your car, no matter what you do you won't go any faster without a good set of tires. Good street tires = Falken RT615, Bridgestone RE-01, Kumho MX, Dunlop Z1.

i have run 615s and rs2s and es100s(sucked *****) fuzion zr1s avons sumitomo... alot of different tires.... Im not trying to come off as an staunch *** but i know the rx7 needs more stuff beyond tires because i have run horrible tire combinations on my rx7 and s2k and i adjust appropriately i have yet to run really good street tires on the rx7 but i feel the worlds difference.

when i bought my s2k it was a scary instant connection flawless response and handling except for being slow as ***** but when it came to cornering/balence i still beat my rx7 with 300 rwhp all day long and felt safer doing it. i have driven some awesome cars but sadly my fc needs something and i cant really nail it so im trying to attack rigidity first to achieve some kind of very consistent rock steadiness to it. sometimes i feel like im putting my money into the wrong pot. i just love my fc(its a sickening ) i have always been the one to spank the porsche at PCA events in my 80s car and i love being the underdog but damn the s2k just shines on all tires and all brake combos i though at it.. i figure how to drive it. the rx7 for me feels like a constant battle between understeer and oversteer more than it should be.

I have thought about getting another fc chassis and transfering EVERYTHING over

No contest stock for stock. FCs are more predictable when driving at the limit but have struts instead of double wishbones. S2000 has the same 50/50 weight distribution. Obviously you can easily modify the FC to be faster than the S2K.

The only way I see it happening would be if you were to strip the FC and put on a set of R compounds.

You can always get a Miata and set it up.

It helps that the S2k doesn't have as much torque (much like a RX-8) so you don't have to worry about the car breaking loose in the turn like a turbo'd rotary and toeing in the throttle at apex. I've always thought my 91, with barely over stock hp felt more comfortable at speed in the same turn than my 340+ rwhp FD. Main reason is I don't want to wreck the FD and just nut up but the FC does nicely since I don't care as much..or something subjective like that.

Stiffen the chassis, expanding foam works miracles.

I agree that chassis stiffening is probably what you are after. However, I'm not a fan of the foam way. I would suggest more/better bracing like the AutoExe braces:

Use both the chassis can never be to stiff.

my 2000 s2000 is known for being way more twitchy. But i take to it really well because my rx7 is even more twitchy. ill look into the foam i kinda forgot about that.
