I was just wondering, for like a 300whp street drivable drag EK, should i bother to go all out in suspension since i will be driving in a straight line? Or should i stick with just a good spring swap.

I'd suggest pillowball mounts or something of the sort but i'm not exactly sure what an ek's suspension looks like.

I was going to bite the bullet and get some TEIN super street dampers w/ pb mounts and an EDFC (electronic dampening force controller) since my local tuner shop has them exclusively in the area (no shipping costs) but either way I think i'm going tein.

But since i figure it'll be going in a stright line, and my other si would be my secondary/circuit car if at all so i should spend suspension $$ there maybe..

 

From the question's you have been posting around here it sounds like you have too much money than you know what to do with.


On my ek i have kyb agx and tein s. tech springs. I just wanted it for looks cause this car would basically never see the track. I would suggest KYB AGX Adjustable struts with a set of H&R race springs. They drop the car 2.5 front and 2.3 rear. Or they have a sport setup that drops 1.75 front and 1.5 rear. The only thing i am going to change on mine is the springs maybe. the s. tech are quite soft. If i could see a picture if the h&r race springs on an ek coupe i will decide.

 

Lol, yeah I've had my 93' si for a while now, but I was in an accident and claimed a bit of dough, and since i was already interested in auto's and the such i figured it'd be some good hands on as i'm getting ready for school, being i'll have another car. So aside my neccesities (school, investing etc.) i have about 10 grand to spend on a car, and i already have paint and rims selected along with the interior and exterior pieces. I'm now finihsing up on a turbo setup and needed this spring info.

What i was needing to know is do you think it would be cost effective to buy a set of coilovers, in the idea of comfort and racing. Basically, is the car sporty enough, yet comfortable enough but able to also withstand some throw around. I'm also looking at mabe getting them for 100 bucks cheaper off of ebay (they want 1,300 from tein themselves.)

ANy other input would be cool!

 

coilovers would be a good investment....this way for the dragstrip you could raise the rear end of the car so that on launch the front wont raise so high. the front raising so high will lose traction since that makes the rear sag. make sense???? good...because it has never made a diffrence in my 60 foot times when i do it. lol so basically since you are going turbo...i would suggest you figure out how to have turbo lag help you with traction problems. sway bars help a lot too....they help to equal the force between side to side and you can kind of think of those as springs.

 

Yeah i was looking into a traction bar, assuming that would help, along with the obvious sturt tower bar, and all the other strut/sway bars in front/rear.

And i was also alreayd understanding that with a boosted t3/t04 b18c1 in an EK would need a tad bit of lag to help me out of the hole. But i guess i should stick with the Tien SS w/ Pillowball Mounts and the EDFC then! Now i just gotta find for as cheap as possible..

 

That's actually a bad idea. Cause when you raise the rear of the car it causes toe-in. Too much toe in will just drag the rear tires causing slower times.

 

actaully it would create toe-out for the front and toe- in for the rear along with camber issues as well. and i did say that it never made a diffrence in my 60 foot times but sorry that i didnt clarify the importance of swaybars over coilovers. i have a weird way of putting things into perspective sometimes

 

I would not recommend Teins for the track. The spring rates are not very stiff and they don't offer much strut adjustability unless you go with very high end kit from them where you can dial in rebound and compression separately.

The Koni Yellow and GC setup is the best bang for the buck and with custom spring rates, you can pick a rate that will be both comfortable for the street, but pretty aggressive on the track. If you are very serious about it, a stiff rate spring with a set of revalved Koni Yellows will out perform a set of comparably priced Tein coilovers.

The EDFC is a nice gimmick, but for the price, I will just get out of the car and adjust the shocks myself. It takes less than a minute, so the EDFC is not really saving you time.

I just upgraded from a basic KYB GR2 shock and Neuspeed Sport spring setup to a set of GC 350F, 450R Koni Yellow setup and it is like night and day. I no longer have traction issues and the car rides like it is on rails. The spring rate is still very streetable and with the shocks adjusted properly, it is probably more comfortable than the last setup.

 

There is no side to side movement in a drag race, so sway bars are worthless.

Stiffer springs or stiffer shock settings in the back would make more sense than raising it. Not only will it mess with the toe like CivicSiRacer said, but it won't do anything to prevent the weight from being shifted back onto the soft rear suspension.

 

sway bars affect wheel hop. sway bars are springs. the push and pull on each other when installed correctly. if he is running a stock suspension.....and doesnt wnat to fork out money for coilovers...this is a really good alternative. and i thought this is what he was asking....."is buying coilovers worth it for drag racing?"
