need tips and advice for rear sway bar upgrade

I've got the Goodwin Roadster Sport front and rear bars in hand. I'm hiring out the front bar, the rear I'll do myself.

I've never done this, but others say it is relatively easy, esp. compared to the front. But I need your experience and words of wisdom to install the rear bar.

What else will I need to remove to get in there for the R&R sway bar procedure? Wheels, exhaust? Something else? My car is all stock. A quick youtube check didn't net any videos. Anything you can offer will be helpful, thank you!

Steve.

I did my rear bar in 20 minutes. Wheels on, exhaust in place. It's a piece of cake. Unbolt the links from the old bar and leave them on the car. unbolt the mounting brackets and she's out. When unbolting the links use an allen key in the stud to prevent it from turning when removing the nut. Be sure to use some lube when placing the bushings on the new bar. Silicone paste works well. This will ensure squeak free operation.

The front bar, as we all know is a different story. Be aware that the arms on the Goodwin front bar are longer than most (they have three adjustment holes). This may require the subframe to be lowered slightly to fit it to the car. And while others were lucky not removing the steering rack, doing so makes life a lot easier. Cheers.

The hardest part of the rear sway bar installation is just getting it centered up properly. It's really a piece of cake.

Centered up, can you elaborate on that? I'd think it is pretty much self correcting by the bolt holes and the brackets.

I installed a Karcepts rear sway bar which is a 3 piece bar so it was really important to get the bar centered. A traditional sway bar may be different if the bushings don't move on the sway bar. If that's the case then it makes it even easier to do. Just mount and go. Have you gotten under your car yet and taken a look at how it's currently mounted? I think you'll see how easy it is.

Yes, my sway bars are one piece bars (with separate bushings/brackets). I'll be heading under the car maybe by this weekend. I want to get it done shortly before I have the front professionally installed. I found an indy mechanic through the local SCCA group, he came recommended by them. Not only is he a wrencher, he's raced, too, and served as team mechanic.

@stevet . The only thing I can add is be careful of the OEM end links. During extremely spirited driving (Palomar Mountain drive) the left rear end link on my car popped (separated). I have progress technologies swaybars from GWR installed. I have since replaced them with adjustable end links. No issues since (Fiat on the Snake). I’m not saying this will happen to your car, but to listen for clunking and thunking coming from the rear that shouldn’t be there.

Dan, I think your issue was the fact that your car is lowered and the stock end links are fixed for standard ride height. Thus it was putting a lot of stress on the end link. Karcept sway bars come with adjustable end links and they have a very precise formula for adjusting them based on ride height so that tells me it's better to have adjustable end links if your car is lowered.

I hope my mildy lowered car will be ok.

Will install both Eibach sway bars and springs.

Weird note, maybe typo.

It says in the Eibach site that it will lower 0.8 Front yet 1.0 rear.

For the Miata ND it is 0.8 on both and the other sites also claim 0.8 on both for the spider...?
