Speedtech Subframe?

[g356gear]

I haven't seen many guys running the Speedtech sub-frame for the 69 Camaro. Mostly just the DSE units. Cost wise Speedtech has a big advantage and you can use different spindle and control arm set ups on their unit. Sub only weighs 125 lbs as well. Anyone have any feedback with the Speedtech unit as a comparison?

It is a awesome piece and recent performance reports of the Speedtech test car Nova prove it. Out gunned by a few hundred horsepower they are within a couple ticks of the baddest cars on the planet at optima Challenge. 5th overall with 450HP to 500HP at that event is pretty damn impressive!

You being in Canada, even makes it more of a no brainer.

wat is the diferense in weight against the stok frame ,and will it house a pontiac engine!.
also can you run al the other stock stuf stearing box ecetera...and what is the price of a bare frame..thanks

Subframes are for F-bodies and accept small block, big block and LS engines. Sub weighs 125 lbs and in bare steel, cost is $2195

We have had 2-3 customers install pontiac engines including Frank. we do not have motor mounts for the Pontiac as the demand hass been really low. but they wil fit. the Stock Steering BOx is NOT an Option, and the Rack and pinion must be used.

[Roadrage David]

So this rack and pinion works with a pontiac engine!! Thats a first...............manual ore power stearing, and can you buy the supframe bare with the rack and pinion only??.. Thanks

well consider the rack is offered as an upgrade for the stock subframe and takes the place of the steering linkage. so the factory pontiac oil pan would have had to clear the original steering linkage. if your wanting a pontiac engine you will have to fab your own motor mounts and headers.

yes you can buy the sub and rack only

[Roadrage David]

cool what price!!! and what stearing ratio. thanks

[killer69]

The sub is 2195.00 bare including all the hardware, rack and pinion 859.00 14.1 ratio and take into account the steering arms are also slightly shorter than a stock arm so the steering feels faster.

hi, im interested in the speedtech complete sub frame, and from the vancouver area just wondering if you have a showroom and shop in town or is your business done online?

[Roadrage David]

Is the 12.1 ratio availeble as wel.....

yes we do have a shop 1-888-467-1625 give us a call

The DSE and Art Morrison front subframes are both front steer rack & pinion, The SpeedTech subframe is rear steer. I'm wondering if one is preferred over the other. Logically, a front steer arrangement should be stronger since the tie rods would be under an extension load rather than a compression load.

Mij gues is that due to the rear rack and pinion in the rear there is room for the Pontiac engine???

why would you think that LOGICALLY it is stronger? what would make an extension load better than a compression load? in which direction of pull are your connecting rods strongest? there is really no differance in strength. The differance is only in the packaging. Both work equally well.

I would think that due to the way a typical tie rod is designed (especially considering length to cross section) it would be more prone to buckling under compression than failing under extension. From a kinematic standpoint, I could see this popping up as deflection in the tie rods lunder load leading to some strange behavior. Wasn't that why GM moved to front steer on 2nd gens? Of course that's recirculating ball vs. rack and pinion, but the basic physics behind the two should be the same, if perhaps to different extents.

This a short discussion on front vs rear steer.

So i was originally planning on using my stock sub. But now im looking for tire clearance, im interested in this subframe for the amount of tire clearance.

On the site, it says any aftermarket control arm made for the stock sub will work. I have SPC uppers and chris alston coilover lowers with ATS spindles. There arent two types of spindle still, is there? (like the tall one and a gulstrand mod one). Curious to know, with this sub, my uppers and 18x9.5 40et(equals 6.8" b/s) with 285 or 295 would i have clearance issues?



Do other aftermarket racks fit since they would be mounting in the same location? i'm looking at a manual rack.

My rear sub mounts are solid now(fixed), the front 2 on the body still have the loose nuts. Do you think i will have alignment issues?
mounts like this:


Definitly interested due to the amount of mods im about to do to my stock sub without any extra tire gain.
