I am going to be upgrading the suspension of my 85' GSL... my plan at this point is to start with the ReSpeed bushing kit http://mrcmfg.com/catalog/product_in...roducts_id=368
_____________________________________

The description is:
This kit is based on: No rear sway bar, larger diameter front sway bar, leaving the stock rubber bushings in the rear upper control arms and only replacing half the watts link bushings.

Kit includes:

* Front control arm bushings.
* Front sway bar end links.
* Front stay rod bushing kit.
* Rear lower control arm bushings (Half the normal kit).
* Watts linkage kit.

On the info I've found the poly bushings are good for up front but too stiff for some of the components in the rear...correct?

So what other bushings, OEM, should I change while the suspension is apart?

I plan on keeping my stock front swaybar for the moment, so I am going to purchase the Poly front sway bushings.

This car will be a daily driver with spirited driving and MAYBE? some auto X in the future

Thanks

 

Billy (from Respeed) knows his stuff, so you can trust his judgement on this. The items included in his kit were also influenced by input from members of this forum, based on their personal experience.

Leaving the stock rubber bushings in the upper rear control arms, and in half of the watts linkage, is to avoid binding in the rear end.

He's already done the homework for you. When I started building my car for autocross, I told him I wanted a car that could kill Miatas, but still be driven to work everyday. I followed his recommendations to the letter, and ended up with exactly what I had asked for. You simply can't beat that kind of service...

thanks Kentetsu,

I have seen alot of good suspension info from you...and Billy. The proof is in your vids...very impressive.

I plan on adding an arsenal of ReSpeed products over the next few months. Do you know which bushings in the watts linkage I'll need to source from Mazda?

 

Thank you for the kind words.

I believe you can get those from Respeed as well. Here is a link to the Respeed forum, probably the easiest way to get the info you need:
