looks pretty sweet. keep us updated with this as you drive on it more.

UHMW is a very tough material, with the highest impact strength of any thermoplastic presently made. It is highly resistant to corrosive chemicals, with exception of oxidizing acids. It has extremely low moisture absorption, very low coefficient of friction, is self lubricating and is highly resistant to abrasion (15 times more resistant to abrasion than carbon steel). Its coefficient of friction is significantly lower than that of nylon and acetal, and is comparable to teflon, but UHMWPE has better abrasion resistance than teflon. It is odorless, tasteless, and nontoxic.

I can vouch for the tasteless part. lol!

I can hardly notice any more cabin vibration but i do dissconnect my torque damper when i'm not racing and i've yet been able to test the wheel hop reduction.

We would get UHMW from a local industrial plastic supply company and it comes in sheets so any one that uses it will probably have small scraps laying around that u can grab for free.  Or I guess I could just mail some out to people too.

I'll update any thing that comes up over the next few weeks.

BTW-All i had was white but it is availible in other colors as well, Black & white being the most common.

yea, i'd def be interested in a set of these if you come by enough for all the crossmember bolts. if you could cut them up and stuff i'd pay for your labor and shipping. i dont have a hole saw or anything

Hmm,  I smell lucritive buisness venture...j/k

I'm gonna try punching them on my iron worker so i can pump them out in seconds plus it would make much cleaner cuts.  If mine don't end up causing any issues I got no problem shipping them out.  I'll search around for some black but white is all I got right now.

its 8 per set, so one on top of the crossmember and 1 below it for each bolt right?

im interested, but i gotta check how much its gonna cost me to tap and rethread two crossmember bolts first so maybe ill pick up a set the next batch or if these are still available next week

Fuck it, I'll try anything.  My cross member hasnt been torqued yet after doing my mmi's and the washer thing, plust my crosmember is way low just sitting on my tanabe underbrace, so I'll give it a try. Send me PM

K, all prototypes have been claimed now we'll wait and see how they work out.

BTW- I installed them one end at a time and did not need to unbolt motor mount from engine or anything, real easy intstall.

Haven't tried with a/c on, I'll let ya know...would be nice to get a back massage after work though...

how are the vibrations with the AC on. I have solid polyurethane motor mounts, torque damper, bsr and I have metal washers in place of the rubber bushings that your UHMW ones replace. I the vibrations seem very minimal at idle, but when I turn on the AC, the car turns into a fucking back massaging machine!!!

I tried with a/c on and had no extra vibration at all.  I also have mmi's and bsr but keep in mind I dissconnect my torque damper when I'm not racing.

it will really depend on what your idle is set at. if it's slightly higher, the vibrations will be less harsh.

props on getting something less ghetto than home depot washers going for this

one of the reasons i did the original mod with all the washers above the crossmember is to drop the engine down as low as possible for lower center of gravity.

Ahh, I never thought of that, I do have 3/8" and 1/2" thick UHMW plus I guess u could put both 1/4" washers above the cross member as well.  When I was thinking of using the stack of steel washers I just imagined my fat fingers dropping them all over the floor so thats what started the idea of just using one piece of something thicker.  If any one wants to try thicker washers let me know.  I also have a CNC Highdef Plasma table so anyone dead set on using steel I could cut them out of anything up to 1" thick. Steel, Aluminum, or Stainless Steel-(if you're made of money-lol!)

UPDATE!!!

I got these in the mail this morning and installed them right away. Fairly easy install. The back 2 crossmember bolts were the toughest. The only thing i had to do was expand the hole on the UHMW washers.
I took the car out for a little joy ride afterwards. Wow!!! What a difference. So much smoother downshifting and very little to no wheel hop. I did a couple launches as well. Not just the typical launches(2-3K). I did a few at 4-5K also where the wheel hop is bad! I am very impressed. The car feels much more smoother through all shifts. Also i havent really noticed any increase in vibrations.

I highly recommend these!

Also i will keep this thread updated with my future findings.

hmmm nice. where can you get this material? how much would you need to ship some out to TX.

I's be interested in a set as well.

This is probably the only thing that the Butt-Dyno is actually accurate at reading.

so you upgraded these from stock right? im interested in some results from someone with the metal washers going to these

I forgot to mention this. I had the metal washers only on the front before this. I took it out for a drive after i replaced the metal washers with these. I felt a slight difference in the UHMW. Going from the metal to these, the vibrations are cut down a lot too.

Id be iterested in a set for sure. My rubber bushings looked horrible when I put in my mmi's I'd love to get something cleaner in there.

im interested in trying these out, ill paypal you $5 and pm u my address

I wanna set as well.

and thus, the birth of the $5 wheel hop aid

No shit eh! lol


I came into work early today and did up a bunch of 1/2" washers I think these will be the way to go.  I found a nice density of UHMW that punched real cleanly but it is still the ugly white color.

So if you want a set of (4) 1/2" washers just paypal me $5 (rob_silvester@hotmail.com). Be sure to include you address and spec-v user name so I can keep things orginized.

Just to let you know I will be gone next week so I will resume shipping on Monday the 18th.


P.S.  Don't forget to give some feed back after you install them cause like I stated before these are pretty much untested and I am just ASSUMING that they will work with no issues.

$5 sent.

ooh im down for a set, this still good?

I got mine a couple of days ago, but haven't had time to install them yet. I will probably do it either thursday or this weekend.
