Default Solid Subframe Mounts!!! Check this Out!!!

So I know some of you guys on here are always looking for Sub Frame mounts. Well Iím going to be making some solid Sub Frame mounts for the 06/07 Sub Frame here soon. Since these rubber mounts are crap, and are a huge contributor to the wheel hop issues that the Vís have.

If you any of you are interested and want to do a group buy I can probably get the price down around $200-250 for a set. Before I get a batch made though I want to gauge, and see how many of you are interested in this. If I can get at least 5 people who want to try these out I'll make a batch here in about a week or two, and get a final price nailed down if anyone is interested. If this proves to be something that works well I'll start making more and selling these.

I would be interested. I think this might be why i feel the *** end wiggle around like its washing out on hard turns. And no... Its not my tires or imagination. Something back there is letting the car get kinda wishy washy when i push it in the turns.... Primarily right hand turns when the *** is being pushed left...

Didn't you have that issue with your last V?

Yeah. On the last car I thought it could have been caused by the cut springs but on this one, the suspension is all still stock at this point and it does it too. Something back there is allowing things to move around a little. Im assuming bad bushings somewhere or something. I really dont know. The car feels planted at all times other than on hard right turns. I get that wishy washy feeling where it feels like its washing out in the rear but catches and does it again and again until i get out of the turn. Feels like the tire rolling on the rim but its not. I really have no clue what it is.

I'd suspect trailing arm bushings before subframe.

Back on topic: I'd be a little afraid of the amount of harshness added with solid mounts.

Well then ill wait until i install my ground control kit with MM spacers, MAP trailing arms, etc before i look into anything else. Might fix the problem with the new MAP arms.

I'm curious myself as to the risk involved... at what point do you start ripping **** apart because of too much rigidity?

I think it would be too firm.

I did a combination of filling the voids on mine with 65a rubber and adding the diy washers on top and bottom. It was firm as hell.. I did it for handling improvement, not wheel hop. Definitely worked for both of those but it was way too firm for the rest of the drivetrain and clunking bad so I ended up taking out one of my washer layers and it's nice now.

I thought my diff bushing was shot but it looked brand new. I realized the cradle needs to flex a bit to subdue the diff slack and create a smoother shift.

I did get a cs bushing and block but ended up only installing the block.

My trailing arm bushings are shot. I plan on picking up some of the turn in concepts bushings soon.

What did they do on the factory race cars? Did they tie the cradle in with the cage?

We need a vendor to make Poly bushings for the rear carrier. Solid would be too harsh

Down for poly. Not sure on solid either, Max at CS said he was making some poly but that has to be over a year ago I heard anything.

When I ordered my 8.8 kit in May he said he was in the testing stage with these bushings

I agree that for a daily it will be a little rough. This was more in mind for the road race and big HP guys because we took a go pro vid before I tore my V all apart again and the flex under acceleration was really bad, and my mounts were still in good shape.

Poly mounts though I think will not much softer or smoother than solid because everytime i've switched between poly and solid mounts I can barely tell a difference if any.

I wont be able to test it out though for at least another month I just sent my ls3 of to be stroked, forged, and low comp pistons. I'm gonna though here in a week or so start on the mounts so if anyone is seriously interested PM me.

I may still be in for solid if you review them once you got them in, or if someone else does.

I can see this being the case.. My mod was a bit ghettto but it worked well. It was very solid yet forgiving on nvh because I sandwiched rubber in there and gave it all nowhere to go with the washers, so there was never true contact between the frame and cradle other than the bolt housing of course.

The bushings I've seen, especially those terrible oem ones, just fused more surface area together without firming the stock bushing void itself. For example, the side height of the bushing seemed to prevent the compression itself, depending on how firm they are...

Once I took it apart it all made sense. I'll post some pics later if anyone is interested

i know exactly what your talking about.. oem TSB bushings are pointless.. white ones
Click the image to open in full size.

the SW bushings def add noise but work.. what's different about your setup other then filling the voids with poly instead of an insert.. post some pics if you get a chance

Been running my sort of half solid cradle bushing helpers for 2 years. Basically 2 thick (close to an inch) washers on top and bottom with some rubber in the middle.

No nice way of putting it but by far the largest contributor of noise and harshness BUT they do tighten up the handling tremendously in my opinion. No real change in hop. They are LOUD. Really they are. I almost decided to remove them at one point but too much hassle as I had to cut the stock rubber ones quite a bit.

So I can only imagine what solid ones will be like.

That is what one should expect when you take the comfy cushy stock suspension and turn it into a hot rod/go-cart.

Just replacing the rear strut supports with sphericals (no rubber) tightened the feel up.
