Default So that's is why car is so stiff.(FE7)

As I was replacing my front susp. Ball joints,bushings and shocks I realized that my car has the performance susp. Option. 1 and an eighth in front sway bar,rear sway bar and 7 leaf rear spring.I find it odd that a 1978 L48 auto would be optioned as such but all the FE7 stuff is there.

My 78 L48 auto was originally a gymkhana car as well. The base cars ride a lot nicer in comparison.

Go here http://www.corvetteactioncenter.com/...x.php?cmd=area and see if you can obtain a copy of the original dealer invoice for your car. The invoice will list the options installed on your car when it left St. Louis.

Doesn't gymkhana loosely translate to "rides like lumber truck"

I actually like the Gymkhana suspension. Great handling, sure you feel every bump, but if it isnt a daily driver, its great! Im actually gonna change the setup on my 82, like I did on the first 82 I had. 550lb coils in front, with a 360# monoleaf spring in rear, and Bilstein Sport shocks.

A set of Bilsteins would likely make the OP feel differently about the FE7.

They definitely made my FE7 (with 360# fiberglass rear) setup feel (a lot) better, but it was still no comparison to the base suspension car I rode in with some no-name shocks. That felt like a Cadillac in comparison. Of course, this is a Corvette... there's a reason mine rides rough.

IMHO, having run 4 different front spring rates on my shark over the years, including Daytona 860's, I consider the FE7 ones only a moderate rate. (BBSS subscribers, please just look the other way.)

It sure does. The rough ride was one of the things that made me hesitate when I bought my '79. Asked for advice on softening up the ride and lots of people told me there was nothing to be done about it and said I was stupid to expect better. Fortunately I found out they were wrong.

Sadly...too many times blinder people will tell someone that it can't be done or they are wrong,
Then some people like yourself thinks beyond that and makes it happen.

I personally think the gymkhana option was trying to appeal to people who wanted extra performance, GM wasn't about to boost HP so slap on a stiff handling package...
( was it a hot seller ? )

Someone posted recently that almost every L82 C3 had the gymkhana suspension but not many L48's. I don't know if there's any truth to that or not.

I had an 87 car, originally Z52 but they added 84 Z51 springs... by comparison, yes, FE7s are moderate. But 300/150 is a stark difference from 550/300.

I'm not a BBSS subscriber, fwiw. Springs do things beyond roll control that sway bars simply can not do.

I should clarify; my car rides "firm", but not intolerable. There are situations where it sucks (really torn up roads, loose pavement), but it's good on most roads in reasonable conditions. The base springs are night-and-day though, IMO.

Yes, indeed they do. Of course, tho I hate to admit, many are those who never push a C3 hard enough to notice. For them soft to medium springs will do, and I have no problem with that.

And, FWIW, my snarky BBSS remark wasn't aimed your direction, nor anyone else's posting on this thread, thus far.

So, I have a 75 L82 - how can I identify the difference between the suspension packages? I know it has the more "robust" automatic transmission.

Its been a while since I looked into this. I know the front sway bar is thicker on the FE7 suspension than it is on the base suspension but I don't recall the exact dimensions. If I recall correctly (and I'm far from sure about this) I think the FE7 suspension has a rear sway bar and the base suspension does not.

I did some looking and the base suspension does not have a rear sway bar while the heavy duty suspension does and also has a 1 &1/8 inch or 1& 3/32 inch front sway bar.

Just because you don't want your Corvette to ride like it does with an FE7 suspension doesn't mean you need to drive a Cadillac. This is not an all or nothing situation, many people not liking the FE7 suspension will find the base suspension just fine.

Certainly not my area of expertise - so how does that info compare with what can be seen in these photos I took?
