those poly bushings are going to bind to **** if those camber links are shorter than stock

 

He's got the PBM links, so they are shorter. I believe that the only real solution is to run spherical, or stock bushings to prevent binding.

 

Correct.

 

has anyone used the gold heat tape on an FC? was thinking of covering lower firewall, and near turbo?

 

so it should be fine?

 

bought some gold heat tape to try to keep some of the heat from going into the car from engine bay, and to try and keep some of the coolant lines near the turbo from heating up. hope it works!!
also painted the engine bay Gunmetal, hoping that it looks good once i paint the car that Teal colour.

 

The links are not the issue. The control arm bushings themselves are. On stock height, or a modest drop, the polymer bushings are ok in the control arms. On really anything more than an inch or two, you will probably have binding on the rear control arms due to the stiff bushings. The stock bushings are $25 a piece and you need 4 of them. The sperical kit is about $350 last i checked.

It's more of an issue if you are doing competitive driving like auto cross and such. The suspension binding makes the rear end a little squirrely. It can also hog out the bushings early and wear early.

Here's a link to a good rundown of the rear suspension: https://www.rx7club.com/2nd-generati...ified-1067114/

By shortening the camber links, it stresses the rear bushings quite a bit if they are stiff. I personally am going to try and stick to stock length ones, but put Whiteline camber bushings in the knuckle. We'll see how it goes when I get my car together in the next 1-25 years

 

good to know for when i build my fc's rear end

 

It looks like your friend threw the PBM catalog at it. You really should do all parts they offer to avoid binding. These are the spherical bearings I mentioned. The price is lower than I remembered.

here's my recent thread about the same issues: https://www.rx7club.com/2nd-generati...tions-1109335/

 

ok i will let him know that he will most likely either need to pull polys out our replace them next winter.
thanks!

 

so over the time i have been not posting on here i finished the Blue FCs PBM rear end.
i have gotten my t2 swap tuned by Garage Life (awesome and very helpful guy). and got some sick shots of the car.

 

Some more

Recently pared up with BC-fab Motorsports to design and produce some nice FC parts i will have more info and pictures soon. he was fabricating me a fan shroud and exhaust and some bracing. also hopefully some other new things soon.

 

well its been a while..

things have changed
- i moved again
- i own more Mazdas
bought a 2018 MX-5
then bought a 2012 Mazda5 because i needed a winter car/ more practical car in case i needed to pick up or drop off my kid
- i work for a mazda dealership so i can get parts cheap!

lots of updates but waiting to finish unpacking and can clean up my shop
