Guru Newb 7 Posts Member since: 2009/3/12 22:50	Well this seems like the best place to ask, the CF Tech section is a ghost town. I'm in the process of installing this new Dana 44 rear but ran into a few problems. This rear came out of a 90's Vette, mine is an '86. The end knuckles are very different and after searching around it seems GM changed the size of them increasing them 1" which will screw up my wheel offset (I think). I had my wheels custom made with the early 84-87 offsets. So can I just use my existing knuckles? It also appears my ABS brake mounting location is different? The parking brake cable mounting location also looks very different, any ideas of re-routing it on this new rear? The coilovers were a freebee and I'd love to mount them but they are for a FX3 setup, anyway I can still mount them? Any pics of your early coilover/ rear would be very helpful.

I presume it's an automatic with the D36? The easy way is to keep your offset correct is reuse most of the 86 parts. Just swap in the Dana 44 and batwing and sell those 90 knuckles and brakes. All your spherical links will fit it too. You can also swap in those bearings if they're any better condition than what you have now. You might also have to steal the longer lower shock studs off the 90 setup, otherwise the coils might interfere with the dogbones. The only real downside is you end up with a slightly smaller rotor (11.5" vs. 12") but performance-wise, the car won't know the difference. I don't know who's swapped knuckles to the 88+ design. Honestly I don't see why it can't be done. All the attachment points to the car are the same as far as I know, with exception of the upper shock mounts and length of the parking brake line.

Perhaps you can find a rod end to thread on there, assuming it doesn't cause issues with shock travel or anything. If you have the FX3 actuators, they're worth something to someone. Actually, since those appear to be stock '90 Bilsteins with retrofit coil overs, so why can't you just install them onto your 86 shocks instead?

You can try your wheels on the suspension to check to see if the tires rub on the fenders. Different wheels may be the most expedient solution if there is interference. Otherwise you should be able to install your old knuckles and spindles on the new suspension. That would take care of the e brake hook up and the ABS sensors. If you keep the late knuckles, I suspect the new Abs sensors will work with your ABS. The later e brake is incorporated into the brake caliper, rather than being a separate drum brake behind and inside of the disc. You would have to go to the later calipers and probably e brake cable to connect the park brake. Just a little insight. RACE ON!!!

Yes I do have my stock suspension on the car, it is a D36. Damn I was really hoping to just throw the whole thing in but it looks like the least painful way is to just swap my old knuckles onto the newer batwing and dana 44. The shocks are from Exotic Muscle and have the FX3 actuators and from what I gather are quite expensive, but I got them for pretty much nothing. Maybe for know I'll just keep my old Bilsteins and sell the coilovers, buy the correct ones at a later date. Live and learn...

The suspension for any given year is the same between a D36 and a D44. The diff and the batwing are the only parts in the suspension that are different. The problems you are having with component interchange and hook up is year related and not D36/D44 compatibility. The simplest way to a D44 conversion is, as you said, to use the D44 diff and batwing. The other parts, the half shafts, camber rods, and tie rods, either from the picture or what is already on the car should work equally well. I "ass-u-me" you have the "C" beam and drive shaft under control. RACE ON!!!

Good question, I can't figure it out at all. Every coilover shock I've worked with, the threads are part of the tube. And most shocks that I can picture have straight, smooth tubes. So it's puzzleing how the black, threaded portion stays on.

The rims in the rear are 11" The coilovers have a ring (bottom) that threads onto the shock holding the spring.

Actually, you may not have needed to buy both. The "C" beam can be drilled for the shorter set of holes. Since the diff is stationary, there is little to no slip needed at the slip yoke. I know of several people that have used the "too long" automatic drive shaft with the D44. Quote: BrianCunningham wrote: check the halfshaft length compared to what's on the car.

No, if the way it's been described is accurate, that the threaded part for the coilover (where you adjust ride height) is slipped over the shockbody and held there with a snapring, then I wouldn't use it. I may be wrong but that's what the description sounds like.

I like to keep a couple sets in stock. Well due to my mess up, we double ordered shocks. We have 3 sets of coilovers that we would like to move. This includes 4 "marlin" Valved Bilstein shocks, springs, hats, shock bushings, adjusting nuts and sleeves, spanner wrench. All for 1495 dollars, our normal price on this package is 1695. [IMG]http://www.dougrippie.com/images/11-c.jpg[/IMG] Order soon, because there is only 3 sets that I can offer that this price!!! If you are interested in all the poly bushings we can work that out on a case by case deal. Thanks Randy [url]www.dougrippie.com[/url] 763-477-9272[/QUOTE]

This is pretty much how all of the C4 coil-over kits were made, DRM, Guldstrand, etc.

I would at least hook the end of the collar over the top of the shock body. Why do you think so? It really only has to support shear loads equivilant to those that the spring would support, probably not more than 2 or 3 times the static load of the shock, (about 800 lbs in the normal case). My rear knuckle failed years ago, so clearly the snap ring can handle standard and shock loading above and beyond what the knuckle itself can. A system is only as good as its weakest link. I'm not saying that there isn't a better way, just that this system is not going to fail or be less robust than the factory design.

It's interesting that no one made a more robust set-up for the C4. I guess there just wasn't a tuner market for the car. The ones Brian pictured were just released last year, if I remember correctly. I'd like to see what the pros were using 10 years ago when the C4 was competitive. Was there a better coil over setup, or were they just keeping the leaf springs? I'll see if Randy over on CF knows. The C5 has received royal treatment from day 1, I guess it was recognized as the better car quickly.

The upper shock mount requires a "minor" spread to accomodate the hat/spring and I stress "minor"!The spread required for the QA1 is "less"!

Look more "closely". The "ring" is a bit "darker" than the sleeve in the snapshot. A quality shock is NOT "thin walled"! This is a very "tried and true" install that's done by many builders!Here's a link to an Afco kit for their "smooth bodied" shocks!I believe the sleeve for the DRM is different and a single "diametered" product with no recess as in the Afco sleeve. http://www.speedwaymotors.com/RS/SR/Product/10620125SB7_R.jpg

The issue is that the sleeve precludes the use of 2.25 inch springs and requires 2.50 inch springs that takes up real estate that you really don't have. Now, if you coil bind the spring, you will damage any spring perch, including the Acme threads on a Penske.

I think these guys are doing it this way strictly for profit using the least expensive shocks they can get away with. You can get coilover shocks for under $100 each (nonadj.) It's interesting that no one made a more robust set-up for the C4. I guess there just wasn't a tuner market for the car. The ones Brian pictured were just released last year, if I remember correctly. I'd like to see what the pros were using 10 years ago when the C4 was competitive. Was there a better coil over setup, or were they just keeping the leaf springs? I'll see if Randy over on CF knows. The C5 has received royal treatment from day 1, I guess it was recognized as the better car quickly. The issue is that C4 guys don't realize that parts for C4's cost the same as C6ZO6's. Most vendors are tired of C4 guys bitching about $$$. I was disgusted when I saw a post by a guy asking Astock65 to GIVE him his drawings for his excellent rear camber/trailing arm setup because he could not afford $300 (like he could do it so much less). I sell 100 sets of C5/C6 seat rails for every one I sell for C4's. My old boss at Lockheed used to say: "don't waste your time briefing someone that has no money".

The problem is that many C4 owners are doing so on the cheap - re: budget. I have seen so many C5 and C6 owners simply write big checks for their mods... and keep doing so... it's like an addiction. However, C4 guys can't afford to buy a C5, so they compromise, get the C4, and fantacize about getting that C5, so they don't buy anything for their C4. I have seen that waaaaay too many times. It's odd... the C4 is a DAMNED fine platform. It can do very well and there is still this perception that it is some kinda bastard stepchild.

Most vendors are tired of C4 guys bitching about $$$. That's certainly true in many cases, Gary, but in this case the C4 coilover packages are the same ones that came out 10 years ago when the C4 was the new car. I understand why few companies develop new parts for the older cars now, but back then you had the C4 guys writing the big checks... It's odd that the coilovers were done this way back then. And Andy, I'll agree that the C4 is a capable platform and can still be competitive in various Auto-X classes, but there is no comparison on the open track. They're fast, my car is an example, but it would take a lot of money to get it to keep up with a similarly prepped C5 or C6 (within the rules, of course). For the money it takes to run a C4 and keep up you could buy a C5Z and win. The C5Z will be the car to have in grassroots "big bore" racing for years to come based on its cost to performance ratio - even the C6 doesn't hold a candle. The only reason the T1 guys are starting to migrate forward is due to rule changes intended to keep the cars in the series newer.
