After about 6 months of autox and flat towing in the rain, the plywood spacers were beginning to rot. I had some leftover material from the motor mounts we made earlier this year, and I designed some custom spacers made specifically for our springs. My dad was nice enough to fab them up last week.
A quick test fit shows that they fit perfectly!
I can't wait to test them out at our next autox on the 9th, as long as jimmy and I get the car back together in time.
Another much needed upgrade we've been working on was some Rear sub frame mounts. I took a bunch of Pictures and Measurements from a buddies set of polyurethane mounts before John Installed them on his car.
With some scrap brass tube my dad had lying around his work, and a small piece of UHMW I bought online, we were able to come up with these.
I think they will work perfectly!
For those interested:
Ultra high molecular weight polyethylene (UHMWPE or sometimes shortened to UHMW), also known as high-modulus polyethylene (HMPE) or high-performance polyethylene (HPPE), is a subset of the thermoplastic polyethylene. It has extremely long chains, with molecular weight numbering in the millions, usually between 2 and 6 million. The longer chain serves to transfer load more effectively to the polymer backbone by strengthening intermolecular interactions. This results in a very tough material, with the highest impact strength of any thermoplastic presently made.[citation needed] It is highly resistant to corrosive chemicals, with exception of oxidizing acids. It has extremely low moisture absorption, has a 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 that of Teflon, but UHMWPE has better abrasion resistance than Teflon. It is odorless, tasteless, and nontoxic.
