I am going to a Level 5 setup later this summer, how importnat is this stuff to have, in other words, will this work really well, really bad, or not make a difference with the Level 5 half shafts?

Thank you.

Thank you.

I'm not familiar with a Level 5 set-up because I'm a road racer type. Isn't the Level 5 stuff for the straight line guys?

For maximum wheel hop reduction, it is imperative you remove ALL rubber from your IRS including the (cradle) sub-frame, control arms and diff mounts.

Just as a warning, the Aluminum front diff mounts can be a little noisy for a daily driver. The other components will increase NVH to a certian degree but not much. The IRS will feel like a completely different unit when you're done with this set!

Hope that helps?

It helps, I really like all aspects of racing, I would like to have a versatile enough car to go to the Pocanos, run at auto-x's, and do some dragging too. Maybe I am just dreaming but I wanted to see if these had been shown to work with the level 5 setup. Reducing wheelhop is reducing wheelhop, right?

If you tell me what a Level 5 set-up is, I can give you an idea of if or how much this set will improve it?

My wheel hop reduced 90% with this set-up. There is still a tiny but but nothing I can't handle? But then again, I don't drag race at all and only drop the hammer occasionally.

The level 5 half shafts here: http://www.driveshaftshop.com/MUSTANGC.V..ivnu

That is what I am looking at, I just don't know how well yours will work with it or clash with it. If they will work with it I am in like Flynt.

Well, if it's just the half shaft they have nothing to do with affecting anything regarding the control arm bushings, diff or cradle mounts.

I have had no durability issues with the Ford '03 halfshaft with the exception of the outer boots. Now that I vent the outer boot on the left side, I don't blow any more boot seals. Granted, I'm a road racer.

The guys that run very high HP straight line cars probably need a heavier halfshaft? I'd like to try a lighter one to tell you the truth!

[Juice33]

I believe these are lighter, they are stronger though. I could be wrong. How long (or how many) more sets do you have? I am going to research this a little more and I might buy your setup.

Thanks for all the help.

I probably have about 10 sets or so, give or take? They have been moving quite regularly.

Let me know!

i might be interested in your bushings. if i gave you a deposit and then payed for the balance in a wekk or so would you hold a set for me? or do you have plenty of them in stock?

There is no problem waiting only a week. They aren't going THAT fast!

ok cool. i have a question. did you sell a set like this to a memeber named sbc.cobra? i started a thread asking about "the red pill" and curing the wheel-hop of the irs. and he responded saying he bought a full dlerin set-up from a member. he mentioned it was a memeber with a cobr-r so i'm assuming it might have been you. if that's the case, then you can count me in for a set. only one other question. the aluminum will be pretty harsh for a dialy driven car wouldn't it? would i be better off buying everythin but the aluminum and then getting something that a little better for NVH? or do you offer delrin instead of the aluminum?

Yep, I sold sbc.cobra his set. And yep, that's me!

The complete set (pictured above) includes EVERYTHING for the IRS including aluminum front diff mounts with shimming washers (to set pinion angle) and rear Delrin diff mount replacing the OEM rubber. Upper and lower Delrin control arm bushings and UHMW cradle (sub-frame) mounts. $595.00 plus freight for the complete set.

Let me know if you have any more questions?

[neckdemon]

ok, sorry to be a pain the ass. but you responded before i could finish editing my post. i'm just a littel concerned about the ride quality with the aluminum diff mounts. do you think they will be suitable for a dily driven cobra? or should i go with everything but the aluminum and just substitute them for delrin or urethane? i just don't want to be driving around on a pogo stick. lol.

Ride quality won't change all that drastically. The pogo stick effect was a direct result of the poorly designed and poorly manufactured bushings marketed by the Brand "N" guy. Precisely why I decided to get into this to prevent others from the pain I went through.

NVH levels will be raised slightly. The greatest offender IS the front Aluminum diff mounts. If you have a car with full interior it won't be too bad? Back seat and carpet block a lot of the noise.

You have to make a decision what you really want out of your car. A quiet soft cushy ride with wheel hop (like Ford delivered to you) or a raised level of NVH with almost complete cure of the dreaded wheel hop? If you have a stereo, turn it up! You probably won't notice ANY difference in ride or noise while cranking out some AC/DC?

Bruce



PS In addition to your edited post: I will not make a Delrin front diff mount. Road racers get their diffs too hot (like me running 240-250 almost all the time with a diff cooler!) The Delrin might get too soft at those temps (?) and I just don't want to take any chances on anyone having any probelms.

Let me put it to you this way, put the Aluminum front diff mounts in and if you don't like them, take them out. Those front diff mounts are not that hard to change after the fact.

[neckdemon]

yeah ok, you're pretty much right. i can deal with a little bit of NVH. especially since i'm usually blasting my radio like you said. one other question, just so i know. i'm assuming that the "cradle" bushings are the same as what has been called "subframe" bushings? just curious because it seems that ford put the wrong size bolts in there. 12mm instead of 14mm. will i be able to install the right size bolts with this set?

Yes. Subframe and cradle = Same-O Same-O. That's why when I call it a cradle, I always have (sub-frame) right behind it in parentheses.

To maximize efficiency of the cradle mounting points, it is highly recommended (as spelled out in the installation instructions) to also get the 14mm bolts (also available from me if you don't have them?) for the front mounting points. The front mounts have a large enough I.D. for the larger 14mm bolt.

[neckdemon]

alright. cool. you can count me in for a complete set. you sure you don't need a deposit? i don't want to find out next week that you don't have any left.

I can assure you it's safe! Send me a PM when you're ready!

[JPIStang]

Are you planning on continuing to make these in the future? I simply don't have the money right now but am certainly interested.

I heard the "N" brand bushings were a nightmare. Are yours going to work as well as the MM bushings (as far as installation I mean)?
