Default im close to my bumpstops

at my current ride height im about 1/2 inch off the bump stops in the rear and less in the front. i havent cut the bump stops yet but i dont realy think it will help. will it or do i need shoter shox? the car seems to handle well(autox as well as hpde) and doesnt 'seem' to be all over the bumpstops but they have to be hittin them all the time being this low.
tia, spenc

set-up
gc's 400f/300r
tokico illumina 3-4f/5r for autox, 3-4 all way around for daily

I'm almost on my bumpstops, but they are pretty tall, and I'm running an assload more spring rate.

You're all over the bumpstops if they're only 1/2" away.

Raise the car up or purchase some stiffer springs.

The rears should be fine, but you will need to raise your car in the front. With 400# on my DC2, I needed to be a little less then 1 inch up front to stay off the bump stops under normal load. Big bumps (like curbing and T10 at CMP for example) still bottom it out, but that is a non issue.

there was a trick to check how much room you should have.. i cant find the thread.

you put something around the shock near the top. then you do your autox/hpde run or whatever, and then you check how far up the thing went. damn i suck at explaining.

I have not noticed much difference, other then the pimpy look and that I can't use my strut tower bar anymore.

Just cut the first notch off of them, but don't do anything like remove them completely--they are there for a reason.

And yeah, you might need to raise the car. Unless you have suspension specifically designed for the car being slammed (which an OTS koni/GC setup is not), you'll run into problems.

RJ, I had about 1 inch of travel on my old car. Stock mounts, OE bump stop cut in half, and A-Arm swap. When I put my setup on the new car, using the GC mounts, I didn't change the location of the spring perch or the snap ring. Only difference is I don't have the upper A-Arms swaped yet. I had less then 1/2 inch. I cut off about 1/3 of the new bump stop and I should be back to where I was. Donno.

Here is your $75 solution. (For those that haven't seen GC's writeup) Still waiting to hear some more feedback on this product before ordering mine. Let us know guys

:edited: last post was created while I was writing mine.

Looks like protest fodder to me. I'd get a definite ruling from the national office before I blew the cash on them.

i don't see why they wouldn't be STS legal? the whole assembly still bolts to the unibody in the same place right?

If you can run JIC, etc JDM dampers which have theor own upper mounts, you can run these.

interesting. i have to look at my shox. i know when i put them in i droped the shock all they way intot he fork as far as it could go. i have to look to see if i can trim something back to get travel. are there any other forks that are shorter than 89-91 civic forks?(although that would only help the front )

-spenc...who is reeaming of all kinds of goodies to fix this travel problem

rear EF shocks have a **** load of travel

If you ever want to see your travel as its hard to look at with the wheel there, put a small spare tire on there and you can see how much travel you have + any spring rates above 600 for sure will keep the rear off the bumstops.
