Default Ground Control

I had these before on my shitty accord a ways back .. thinking of getting them for an s2000 (06) and running stock shocks. I want to do that until the shocks go and then upgrade to coilovers. Does anybody have any feedback on these?

Reason why I am considering these is because Ryan (vtecvoodoo) has them at 315 shipped and thats a relatively good price for some temporary driving. I just cant stock height

btw how much lowered are you guys (that are Daily driving w/o any problems going up driveways and such)

i have been playing around with GC's on my s2000 with an extra set of stock AP1 shocks.

the spring rates im using are 400 front and 375 in the rear. my previous ride height was 26.0" to the top of the fender lining, and now im at 25.5". so exactly .5" drop.

the drop is fine. no excessive scraping. just make sure its even. before i had the rear jacked up too high and drove a bit and it scraped my front since the car was nose diving.

if i had 1" drop in the rear, i would scrape the inner fender, near the back part where it kind of stick out. i hear thats common place ppl shave off to prevent it. but i refuse to molest my chassis. and didnt like it anyway.

the spring [rates] are OK. NOT great, but not horrible either. i actually like it for now. i did go on the track and it did suffer from a lack of damping tho, as it would wobble at corner exit. not sure if the stock shocks im using are worn out from years of daily use before the owner switched them, or if they are overpowered by the springs. but this was ONLY at the track, on high speed turns (70-90 mph). on the street its really fine.

i did swap out the rears for a set of 250 recently thinking it would reduce the load on the shocks. however, i found that to ride WORSE on the street. it would bottom out even going straight on the freeway if there was a dip. just not enough spring for the weight of the car. so i just put my 375's back in the rear and plan on testing out a softer AP2 stock rear swaybar to soften up the turns even more.

hmm i guess ill just buy some Tein CS coilovers from this other member on s2ki then .. hes asking 650 so i guess thats ok.

Its just the stock suspension is worth diddly .. so i was sorta tinkering of using it until the stock shocks kaput.

yeah, pretty much why im messing around with it too. the shocks were free, tossaways from someone who switched to konis. and i had the sleeves from my crx, which needed slight machining to fit, but otherwise work great.

and the springs, well some i have had laying around, some i just got to play with and plan to resell as needed. actually these springs i got from ryan/vtecvoodoo himself too.

i have my original shocks tucked away completely assembled so i can just put it back together whenever.

I have them and love them. Rides great on stock shocks 8K miles later. Easy to adjust, and cheap

you need to replace your shocks with valving to better suit the spring rates you've chosen.

Running the front slightly lower than the rear will improve turn in. Depending on spring rates, the rear will squat on acceleration improving traction. Running spring kits that set ride height front/rear equal or the rear sitting lower than the front wont improve handling but may look better. That's a pretty big generalization but I've found it true since running the rear too low will create problems.

Whats MR Coilovers? I know .. i had some Pss9 on my past M3 and it does make a big differnece, but the stock suspension will be a freaking waste just to be thrown away or sold for diddly ...

looks like ill just get the coils though. Anybody know any good deals?

if you just want your car to look cool i guess you can use ground controls... but if your tracking the dam thing good luck.

spring rates and shock valving work hand and hand... uncontrolled spring equal wheel hop. and undesired rebound.

if you at least buy some quality springs you will get a good ride quality and longer life out of your shocks. no funky *** noises from sleeves or upper perches. plus the cool factor. tein, h&r, or swift racing (my personal fav)

theres nothing less than high quality when it comes to eibach. other than not pleasing jdm fanbois.

really tho, the reason why i am bothering to experiment with GC and different spring rates on stock shocks is firstly because there really isnt any other aftermarket shock alone for the s2000 except koni. im a tokico illumina fan, and theres not a s2000 application. i wish there was. but the fact that not many companies are bothering to make a s2000 application (besides low production numbers) might just have to do with the stock shocks being pretty damn good to start with. and really, without trying it, i wouldnt know how good these stock shocks are.

im not going to use a comparison of other ppls experience with tired, oem shocks on their civics and integras. and simply parrot the dogma of not using stock shocks on aftermarket springs. the s2000 shock is obviously had a lot of thought put into it. just look at the whole suspension, the long front shock and the rear reservoir.

and with GC, you can put whatever spring rate you want. and im not putting tremendously high spring rates compared to stock (if anyone even knows what stock spring rates are). in fact i put lessor spring rates in the rear and i can tell you the ride totally sucked. way too much bottomoing out for being so close to stock ride height.

the second reason i put the GC on the stock shocks is because it was nearly free for me. i had the sleeves, i got the shocks for free and i had springs to play with. i wanted to learn how to swap the shocks, and i can nearly do it in an hour now if i didnt distract myself.

theres nothing lost in putting my GC on my s2000. i got the drop i wanted, the ride improved. and ive learned a lot. i have my ORIGINAL shocks all bundled up, untouched, ready to go whenever i want to go back to stock.

but if you want full coilovers, just go ahead and buy bilsteins pss non adjustable shocks for under a grand. at least the ride height is adjustable. and you dont have to wear out your stock shocks so you can put the stocks ones back on when youre done. dont waste your time and money on intermediary suspension if thats not really what you want.

eibach is of high quality.. while working for a lemans race shop i was use to see eibach replacement springs but every time we changed springs we revalved or swaped shocks and other settings on suspension components.

Eibach springs are cold wound but are not a linear design. (progress spring rates through out compression) eibach springs are made from the highest quality of american metal but our metal quality is not of the standards as any of the highest quality coming out of japan. due to our governments worrying about the environment.

i would buy eibach just because they are always available and an american company.

but Every time i see ground control suspension on someones car i am pulling it out and throwing it away. replacing blown shocks or finding a noise.

eibach springs are made from the highest quality of american metal but our metal quality is not of the standards as any of the highest quality coming out of japan. due to our governments worrying about the environment. wrong we buy a TON of steel from Japan. In fact 100% of our fork springs and valve springs are made from japenese wire here in Corona, CA.

Thanks for the positive comments in regard to our springs. I just wanted to correct those two points.
