Suspension suggestions

I cant blame the track anymore.

I have stock springs, sway bars, and replacement HD shocks. I do have SSM/Jegs bars and Eddy adjust uppers. I have tried ET Streets (bias), ET DR's, and the Hoosier DR's. Just blows the tires off.

What can I do here to get the thing to hook, but still remain 100% streetable? I'm keeping the Hooiser DR's - I like the way these track straight.

Stick car dont forget!!!

Re: Suspension suggestions

I'd try the Edelbrock hop stops. you might need to put stock type lowers though.

do you get rear body lift at launch? any vids from the side?

Re: Suspension suggestions

Right with you Vince. I had tried the UMI Relocate brackets. Didn't really see the improvement I was looking for. I am strongly considering the Art Morrison No-Hops. Don't need a lot of lift in the rear, but do think some would help. But, I kinda wonder if something like a relocated upper is better for an automatic car where you apply power and keep it there as opposed to a stick where the power will be an on/off kinda deal.

Re: Suspension suggestions

I think Vince has already tried no hops....

I would try ladder bars and tube axle in the front....j/k

Vince I think may some drag springs and soft front shocks but it would probably affect drivability.

I still have some NIB eddy no hops if you want to try them.

Re: Suspension suggestions

I had the Eddy no-hops and replaced them with the SSM's. The Eddy's were too violent if that makes sense - they hit the rear to hard, and caused alot of body separation during each gear change.

No vids yet.

Re: Suspension suggestions

I realize the drag shocks and trick springs say not to use them on the street, but I have done so for years - carefully.

I don't drive like a kid in a honda on the streets... I drive knowing my car doesn't handle as good as the car in front of me; cautiously.

Aside from that, you said sway bars... have you considered removing the end links on the front sway bar when you take the car to the track?

100% streetable means something different to everyone. Often sacrifices have to be made to make the car better at the drag strip. Best of luck.

Re: Suspension suggestions

Vince, I have gotten quite a few 1.54 60's. I run stock rear springs, adjustable uppers and boxed lowers and the SS style reinforcement bar all by Edelbrock. QA1's single adjustable shock set at 8 at the track. Back to zero for the street. H&R bar. Up front 289 springs and Koni Classic's set on soft. No front sway bar. Stock control arm bushings and torqued to factory spec's. M/T Drag Radial's @16lbs. Car drives really smooth on the street. Handling would be really good if I put the front sway bar on.

Re: Suspension suggestions

cut 3/4" out of the hop stops and try them again.

jeez, is there enough room to do that?

What a guy really needs is hop stops with adjustable height for the upper bushing.

Re: Suspension suggestions

I agree adjustable good adjustable shocks front and rear Singles should be fine make sure they have as much travel as your suspension ........disconnect sway bar on track day


Stik car right ? Your correct dont need/ want alot of anti squat ( separation) but you can move your IC back some you dont want rear to squat depending on your tires some separation may help, tune that with shocks to allow some extension on launch,fyi with bias slicks mine works best with no separation/ shocks on 80% stiff get car as low as possible in rear ........level with front is great if possible I would reinstall the stock type lower control arms .......rear upper control arms check to see if you can redrill the factory front mounting holes lower ( 66/67 cars you can redrill down 3/4 inch ) that will move you IC back but not as dramatic as no hops none of this will effect street use .......... FWIW

Have you ever tried bias stiff sidewall slicks ??

Re: Suspension suggestions

Re: Suspension suggestions

Car sits pretty level. Rather not get rid of the ssm bars/adjust uppers right now. So shocks make a big difference? Do I need to spend the money for those adjustable shocks? The QA1's are like 150.00 a piece! But if they make a difference, I'll consider them. My front springs are very stiff, but I kinda need them so the car doesnt bottom out driving around.

Re: Suspension suggestions

If you want to get your car to hook and then still have a good street handler then yes decent adjustable shocks should be considered ... allow you to tune for both situations QA1 would not be my 1 st choice ( Like alot here I had them got rid of them ......... you want to keep adj uppers especially if you redrill the mount location .. are those SSM control arms close to parallel with the ground when car a rest ??

Re: Suspension suggestions

the SSM are lowered in the back, not level at all. That's their main claim to fame, what alters the geometry.

Re: Suspension suggestions

I tried the UMI re-lo kit early this year. Maybe right for someone with a different combo, not right for me. Violent hit, destroyed the traction.

I have boxed factory type LCAs, Konis set on stiff, generic rear springs, passenger air bag. Nothin fancy

best of 1.620 using the BFG DRs 275/60 (28 dia), lots of 11.7s
runs 1.63s all day

with a bad track, early FRI, runs 1.7s and 12.0-11.9 so I have mounted up some bigger 295/55 (29 dia) so hope to launch from the get go so as to have performance tuning enhancements rather than suspension tweak every week

betting the taller rubber will get the lca level to the pavement

Re: Suspension suggestions

Yeah, the SSM bars are lower boxed control arms with the arms tilted downwards. I installed them based on a few folk's recommendation here on how good they work, and the fact that they cured my severe wheel hop problem.

Pretty sure I have just about no front end rise as it is. I'm ok w/disconnecting the front sway bar. Shocks - sounds like this should be done regardless. Can you guys recommend some shocks? Even if I have to change them out for race day, so be it - that doesnt take so long to do.
