Ridetech's New 67-69 F Body Subframe

[ajs1luv]

Can you post part #'s for the Rack and Pinion(dse) and steering shaft , and coilovers beening used on this subframe? I'm trying to get all my ducks in a row!

Parts #s?

Any of the Holley pans will fit easily. I have the 302-3 on my car and it’s nowhere close to the crossmember. You can set your engine/trans angle at that, however, -2 to -3 is a more desirable target for any setup. From what I’ve seen over the years, it’s more common to see the tunnel modifications than it is to see a steep engine/trans angles. I hate having any chance of vibrations.

I have one of the Mast swap pans, so a lot like the low profile Holley. I just looked at my notes from when I put the 4 link in, and I ended up with about 2 degrees of u-joint operating angle front and rear. Engine angle is at 3.1 degrees, and the car is nice and smooth at triple digit speeds. I know I could reduce the angles by cutting the tunnel, but I’d like to avoid it since my car has almost all its original sheet metal. I guess I’m just trying to figure out if it’ll be doable if I swap out the subframe.

We haven't used the DSE rack but the subframe is designed for use with a stock Fox Body Mustang rack (any aftermarket Fox rack will work as long as it's to OE sizes/fitment). We've been using the PSC RA33500 and really like it. I have the same one on my car and it feels great (I had the Borgeson box on the stock subframe and the new setup feels tighter/more responsive).

We've been using Borgeson u-joints with the 3/4" DD shaft. We have an adapter setup that works with the factory column already (link here: https://ridetech.com/product/1965-19...-mustang-rack/). If you have an aftermarket column, it'd just need the u-joint with the proper diameter/spline count adapted down to a 3/4" DD shaft.

On the shocks, we'll have our typical HQ and TQ coilovers and shockwaves as an option. We're using our 3.6" stroke shock and see right around 5" of total wheel travel.

090221DS is the part number for the DSE fox rack and pinion. All fox racks are 3/4-36 spline. There are some SN95 racks that are 17mm V in case anyone runs into that.

There is supposed to be a quick ratio rack coming from DSE for the fox bodies that I assume would apply here as well.

Thanks for the info!

Do you have any pics with the subframe installed and the car sitting on the ground?

Thanks, Donnie! I just hadn't dug into their part numbering yet. All of that should fall on just fine.

Yep, just took a picture of one of our guy's '67 at lunch. His is sitting around 2" lower than factory. I'll post up some of my Firebird and another guy's '68 Camaro when I get a chance (they're both sitting around the 2.5"-3" mark lower than factory).

Does the frame come with coil over and the rack? or do those need to be bought separately.

No sir. We let the customer pick out their own rack so they can pick out the brand and ratio that they want. On the shocks, we have our single and triple adjustable coilovers, and the single or triple adjustable Shockwaves as options. These are the main reasons they're not included. Just leaving the end user to fine tune their build and get exactly what they want.

Just to confirm, you are running custom brake lines?

I was able to use the one's that I built for my factory subframe, I just tweaked a couple of the bends. It wasn't different enough that I had to redo them completely.

So, running a 19" by 10" front rim with a 275 tire will be no problem? 6.5" back spacing. I want to pre-order rims and tires. Will I be able to drop the front as low as I want?

That should be just fine, the only difference would be overall diameter clearances. Being the same width/backspace, it'll have all of the same turning capabilities. If you keep something that's 25.5" to 26" overall diameter tire, there would be virtually no difference in our test cars and the size you're wanting to use. The only other factor you would want to look at is if the brakes you choose change track width at all (Wilwood/Baer/etc all mention any changes that their kits will have).

Not sure, but I'm using C-6 ZO6 brakes

275/35/19

In a perfect world, you're safer getting the suspension and brakes fit on the car and then measuring for the wheels. A 275/35-19 is ~26.6" tall vs a 275/35-18 being ~25.6" so clearance will be tighter for sure if that's the tire size you want to run. You may end up needing to modify the inner wheelhouse to fit that tall, however, it would just need to be fit up on the wheels you choose to know for sure.

I currently have a ridetech 4 link with a stock subframe
On my 68 camaro (vert). I'm running Hotchkis subframe connectors. ridetech's frame connectors look similar in appearance. Is there truly any difference between the 2? If it's not necessary to change out I could live with the decision not to change out!

Hey, Josh. What are the specs for the coil over shocks? I'm using a QA1 4-link on my 68 Firebird and want to use matching QA1 front coil overs. Thanks.

The front mount is really the only thing similar. Ours are completely bolt in and the whole leaf spring pocket is integrated into our subframe connector, making it more rigid in all the areas that are prone to flex/move. Those slide over the rear frame rails and have to be welded on.

We use a 3.6" stroke shock on ours. If you have to buy one pair of coilovers anyway, I would definitely look into using our HQ series in the front and rear. The monotube design is going to work much nicer on the street and track (and have a longer life span plus a 1,000,001 mile warranty)

[ajs1luv]

Frame mounts are included, right?
