Some adjustablity in the rear suspension is needed. Being able to adjust toe and camber is VERY important.
Or am I missing something in the pics?

We won't have any toe adjustment but there is some camber adjustment. The rear suspension is lined up perfectly and fully welded.
Now we are working on mounting the front suspension

Over time and depending on things like who's driving it and pot holes etc. it may need adjustment. You can just build new wishbones then.

Or possibly eccentric washers and slotted holes.

The rear suspension is Completely mounted with coil over shocks. Almost have the front mounted, expect that to be tacked to the frame tomorrow.

Today was the last day of the semester and we have a roller. after the break we will work on getting the diff mounted and the other engine related parts mounted.

There will always be some toe-in or toe-out on bump, and depending on design, construction, driver skill, and luck, it'll range somewhere between perfection and completely undrivable. Having it adjustable allows tuning out the above variables, so what you have now is up to chance and driver preference.

We'll take a serious look at adding toe adjustment to the rear.

There are still a couple of things that I don't understand here:
- How can two parallel linkages create toe changes on bump? The only way I can see that happening is if there is misalignment in the pivots. It seems that compliance in the bushings is going to be a much greater factor.

- What's the usual way of adjusting toe with bushed arms? I know there's a bushing with a threaded stud available, but I don't think that's common. Graham mentioned slotted holes and adjustment washers, which seems a good route. But there's a lot of IRS cars out there without Heims (maybe more on the road than the track), so what are they doing?

It's been a while since our last update, but the project has moved forward greatly. we now have the driveshaft cut and welded, seats mounted, diff mounted, complete steering(minus longer control arms), working pedals, break lines ready to be installed after frame is painted, and the fire wall being constructed.

we shortened the miata steering rack as well as the shaft that comes off of the wheel by a lot and now have it mounted in the car and it turns smoothly.
By the end of the week we will hopefully start taking everything back off of the frame so we can prep and paint it before reassembling it and moving toward having a running car. :)

I hope to be able to drive the car before i graduate on May 20th. :cheers:

What a graduation present! Make sure you get a floor in first so that you don't land up with a leg dragged under the car in a parking lot. :) It looks like you'll have it running, but don't get discouraged if you have a lot of details left. I hope you're proud of this effort it's really quite an accomplishment.

:cheers:

Man.... I spent all my time in HS playing with programming computers and look at me now... All I use it for is email and inventory management!!!

If I had been able to play with something like this in HS I just have to wonder what I'd be doing today, because it sure wouldn't be what I'm doing now!!

Congrats on a great looking project! :cheers: <= That's Root Beer for you!!!

I was able to take my car to autocross this weekend and had a great time. Makes me look forward to coming back in the future to race the car when it is finished.

The guys haven't been posting recently - mainly because they've been working like crazy to get the car running by Memorial Day when they finish school. I decided to take a few pictures and update the build log for them.
First pic shows the car stripped down for wiring and brake lines. We were going to paint it, but realized that there will still be a lot to do on the frame. Plus, paint won't get us rolling...
