It wouldn't matter if he cut them or not. Even uncut, the springs are taller when bound than the the effective area of the stop. That's kinda been the point...

I'm not sure if I understood this correctly in an earlier post or not. Are the first batch of copper RCE springs ok as far as coil binding? Also, as someone asked earlier, is RCE engineering doing anything to help out the guys who have the versions that do coil bind?

The copper colored springs are fine. The yellows that followed did have an added coil to be more compliant,but even those measure 13.89mm ( wire diameter) and have 5.8 coils. The original yellows worked fine and offer exceptional performance for the application they were intended for( track day and autocross), but in an ongoing effort to serve a wider range of users we had already decided( meaning prior to this thread) to go back to the 4.8 coil count and thinner wire diameter. The new yellows are improved in this sense and offer a wider range of use for the end user.

In other words, if you have 1st generation yellows, you won't get a free replacement.

Happy driving

What happened to the original name of this thread? Didnt it used to state RCE that coil binds? From what has been stated, it doesnt matter what aftermarket spring you install. The overall travel the shock will allow is too short for lowering. There maybe differences in stiffness, but ALL will bind going over deep dip. The only other alternative is full coilovers.

For those that drive everday, occasional auto-x, drag race, and dont want to spend $2000+ on suspension they will never be able to utilize fully: any aftermarket spring will do.

For those that auto-x frequently or auto-x for a living: full coilovers maybe warranted.

While I did change the title to make it less aggressive, it never specifically called out RCE springs. Remember, this problem is not limited to just RCE Yellows- they just seem to be the most popular, common example.

A user here measured 18mm, are you sure about that? Even in pictures, the coils appear thicker than other springs.

...so long as you stay on a totally smooth course? At least a few members experienced coil bind (and resulting jackhammering effect of the front end) while autocrossing. I don't see how you can claim this. Almost every bad behavior I've encountered on the street happens twice as badly (though perhaps not as frequently) while autocrossing because cornering forces are so much greater (while still having to deal with bumps and elevation changes).

Yes we took a pair of the old yellows and measured them. I will post a pic soon.

Also, if I'm reading between the lines here, does that mean each of the RCE spring variants has a different spring rate for the "soft" progression? (How else would you add a coil and keep a small coil diameter?)

I really like these springs for the track/autox but I'm going back to Pinks.
Heh, mine have been on my car for 1500 miles or so. Going to check on this tonight. I haven't noticed any changes in performance or sound since the day they went on the car, but I'll have a look. I'm not wild about the idea of swapping the springs out again...

^Ya . . .

After stumbling on this thread it makes me wonder especially being up here in MASS. with the worst roads in the world I think. At first the bad roads I thought were jsut the harsh ride and I'd deal with it but with the summer construction going on I've noticed it more and more. I'll check tonight to see if there is any signs.

My question is whats going to happen or be done for all of us that find this on our RCE Yellows??? Spring install is not something that I'd like to have to go through again or pay for twice not mentioning getting springs that don't have this issue. :/

I just got around to getting under my car to check about a clunk/rattle and noticed that my springs are experiencing coil bind. I have the copper colored RCE's and have just been driving my car around on the weekends.

Wow, this is that big of a problem on the RCE yellows that you guys are seeing coil blind this frequently???

If thats the case I gotta throw mine on the lift.

So if one experiences coil bind, then they are going to keep experiencing it? Its not just under one or two extreme circumstances?

Honestly, I think this is BS. When the "Unofficial RCE Spring Review" came out, RCE was touting that these springs were great for DD, track and autocross. If coil binding was a problem for DD, we SHOULD have been told or at least warned of the potential problem. They specifically marketed this spring to the daily driver looking for a cushier ride with better overall performance in handling. I for one will NEVER purchase again from RCE. That's my personal opinion and could care less what anyone else thinks. They made a ton of dough off these springs and we are left with our d**k in our hands just waiting to shell out more dough to fix whatever damage occurs while driving with these springs.

I had a set of the yellows installed in March and I only drive my car on weekends. I know for a fact that I am experiencing coil bind because the car feels like it's bottoming out way more than it ever did with the stock springs. Next Saturday the car is going in to check for the coil bind and I will post pics. Now I have to shell out more dough for different springs or swap back the stockers. Thanks for the waste of money RCE!! You will not get another penny of mine.

In an ongoing effort to make sure that our customers are satisfied with our products, we have made the decision to replace the front springs free of charge for owners of the Version 1 Yellows that are experiencing coil bind. We feel that it is only fair that everyone who is using our springs has the updated version that we will be shipping from here on forward. The manufacturer overnighted us a set of the Version 2 Yellows for inspection and testing and they are now being tested on my car with excellent results. No signs of coil bind whatsoever...I will be taking plenty of pictures tomorrow. So if you have the V1 Yellows and you have coil bind issues, give us a call with your full name and invoice number (if you still have it) and we will send you out a new pair of the updated front springs.
