Dual Mount vs Normal Composite Mono
I recently lowered my 79 using longer spring bolts in the rear but now my tires rub if I hit compression bumps so its finally time for a new rear spring. Definitely going with a composite mono but have been looking at Vbandp's dual mount rear spring. Currently I do not race the car at all but have thought about auto-xing it in the future. Anyone run this and is it worth the extra couple hundred?

is there much difference in price v's performance ( apart from adjustable height) when driving around town. (meduim to slightly hard driving).
Was looking at something like that too. But not in the front. ( too much $$$. ) Mono for those from vb.

I have a single mount rear plastic spring from VBP for some near 18 years now, some years later I put Bilstein shocks on it, instead of the KYB i got early on....HUGE improvement....
I have VBP 460 on the front, and same Bilstein in front too....
I don't go all that fast, just 1/2fast.....

Havent heard anything bad about the dual mount but i use a 360 VBP composite since 1986! Use Bilstein sports in the rear with 550 front springs with Bilstein hd's. Rather than the dual mount rear spring, i would take the money saved and buy competition adjustable struts with heim joints to control unwanted camber movement in the rear.

I have VBP Performance Plus suspension with the dual mount front and rear springs and Bilstein Sport shocks. I have 17x9.5 tires all around with offset trailing arms. I have no issues and handles extremely well

As I understand it, the dual mount mono leaf spring is designed to isolate the action of each side from the other. When one side compresses (going over a significant 'bump') with a single mount spring, there is some amount of stiffening of the other side because of the stretch in the spring at the mount. It is somewhat like having a "built in" stabilizer bar on the rear end. No such action with the dual mount.
I suppose that the road racers prefer the dual mount, as adjustments to either side would not be impacted by wheel action on the other. For street and highway driving, I would think the single mount would be better as you really wouldn't need the stabilizer bar for those environments.

Thanks for the clarification, and your understanding is correct. The difference is in what type of mounts are used with those two spring configurations. The single-mount spring has a rigid mount that cannot pivot. The dual-mount springs use two pivot mounts; that allows the anti-roll 'transfer' to occur. Very interesting.

I was earlier running the 360lb monospring and swapped it for the Dualmount kit and defenetly noted an improvment.
The dualmount is running well both on the street and on the track.
