do I need subframe connectors with 350hp/400tq?

67 Camaro coupe
350 RamJet (350hp/400tq)
stock frame and front clip, front tubular control arms, Hotchkis rear swaybar
handles tight, feels fine to me
should I have subframe connectors?

Absolutely. You will be surprised how much more rigid your car will be with them. I noticed it most when going over railroad tracks at an angle when the car would twist.

Put this in your trunk to reduce flex in the rear. https://www.summitracing.com/parts/h...SABEgKuovD_BwE

I am over 500' of torque and don't have them, but I do not run any type of slick and very seldom launch from a stop

No, you don't need them. Years ago I ran mid 10's at 128 with slicks and no connectors in my '69.

IMO, every first gen would benefit from having SFC's.

My weld in subframe connectors recommended to use solid bushings between the subframe and the body.

Do bolt on type subframe connectors also require solid bushings?

Subframe connectors are not just for drag racing. They stiffen the unibody and improve handling as a result.

Which SFC do you have ?? My Hotchkis came with the new bushings. Bolt-on or weld-on for the front, its users choice. The rears are welded up only.

Never hurts to add them


Suspension is supposed to do the work and if the body flexes, the suspension looses its control over the what the tires are supposed to be doing.

Re: do I need subframe connectors with 350hp/400tq?

I highly recommend SFC's even if you don't think you need them. You will notice a difference for the better.

The idea behind solid bushings with weld-in SFCs is because the connectors need to be removed to R&R subframe bushings, which would require cutting welds to do so. I'd also recommend solid subframe bushings on any first gen, SFCs or not.

I completely agree with you. Does he need them, no. Will they stiffen the car and improve handling. Yes.

I always put a set on my cars I build , they can be a pain in the *** to fit but never hurts to add strength to a car like others have said

Do you use ready-makes or make your own? I seem to recall a old thread with instructions on making your own. Can't find it this morning but the first cup of caffeine hasn't kicked in yet.
