I will out price soon.
My bushings will replace the existing stock rubber subframe bushings.
The stock system consists of 2 parts,subframe bushing and spacer.With my bushings,you will not need spacers at all.

Btw the front ones have been made up,just needs minor adjustments.I will put out the front and rear subframe bushings at the same time.
The mk2 and mk3 supra subframe bushings are almost the same,which are similar to toyota coronas and toyota cressidas.That what I have been told.

So, 5 days and no pics?

Sorry, but I'm EXTREMELY suspicious of someone posting something like this with only 33 posts.

Guys, RonnieK is the RK in the RK FULL Poly Bushing Kit that is available for the MKIII.

There's no doubt he can/will produce these... Give him time.

I'll lend some weight to Ronnie here as well!

I bought a full kit from SupraSport a few years back and they were drop shipped direct from Ronnie and he was brilliant to deal with answering all of my idiot installation questions in a timely manner even supplying a PDF to help with the language barrier ;)

Sorry for delay.I have not been able to access supramania for the last 3 days.
You will get photos next week.
The subframe bushings will be same hardness as rk poly kit which is 90 shore A.
At this stage the price for the rear subframe kit which includes 6 polyurethane bushings with steel sleeves will be $220.00 U.S.
Don't worry I not here to rip people off.I am just a supra owner who was pissed off with the fact that there was no bushing kits out there for the mk3 supra.
I started selling the bushing kits way back in 2003 through Jeff montogery(previous owner of suprasport) and still do.
I have a full time job and I do this part time which is another reason why it is taking some time.
The hardest part is to make the molds for these bushings which I am doing now.Once done,making the bushings will take a lot less time.
I will sort out prices for the front subframe bushings next week.
Thanks,
Ronnie

So, let me get this straight Ronnie....
The subframe bushings you're making are NOT simply the spacers between the subframe and body, but actually the inserts that go INTO the subframe? If this is so, count me in on this!

There's plenty of people to vouch for you, Ronnie. Don't worry about that. Any sort of doubt will be quickly corrected by those who know :D

Hey man,thanks for your support.
Yes,these bushings are not the spacers between subframe and body.Your old rubber subframe bushings will need to be pressed out and replaced with my poly ones.Plus you wont be needing the stock spacers that sit between the body and subframe anymore.

Will they squeek a year or two down the road? I would assume no, because those parts don't have much movement.

Ronnie sent me these pics to post for you guys.

His comments :

1. The steel inner sleeve is not shown,but will be included in the
subframe kit.

2.The bushing is divided into 2 halves,

The half with the flat top sits between body and subframe and the half
with the concave top is the bottom half.

The reason for the bottom half being concave is so people can re-use the the stock bottom subframe plates which the bolt head sits on.

The bottom plate is also concave so it will fit nicely on the poly bushing.


Cheers,
Roy

Wow, this is perfect timing for me as well. I'm definitely in on this one.
The prospect of removing the mushy soggy OE rubber is exciting! :biglaugh:

What steel are you going to use for the sleeves? I'd be willing to pay a wee bit more for 316L rather than plain ol' carbon steel.

I'm most likely in.

if you are looking for longevity of your subframe, opt for carbon steel. Google "galvanic corrosion" or "galvanic series" to find out why.

These are a good upgrade. When you tighten the chasis, the car will handle much better.
