Love the pics of your progress. I'm stuck at work to much to get anything done. I'm living vicariously through your project. Keep up the good work.

I'm super happy with the results, it did take a long time to build but the cost has been pretty minimal.

Looks stubby and beefy as hell.

This weekend I finished the passenger side rear upper control arm which was the final control arm for this project. I had already cut and notched some of the tube whilst making the other side so it came together relatively easy.



I then installed the rear differential and rear axle to get a look at how everything has come together.



Moving forward I have some big purchases to make which may take a bit of time to save some money.

The first thing I need to do is purchase a manual transmission, adapter plate and clutch setup. At this stage I am looking at the BMW ZF 5 speed as the best option, obviously a sequential would be the ultimate but its just not in my budget. The BMW trans seems to be a strong and affordable option, whilst not being too heavy.

With the engine mated up to the trans I can then do all the fabrication around the engine mounts, front crossmember and steering rack.

I also need to get some wheels and tyres.

Thoughts on BMW 7 speed DCT for the BRZ?
A few companies are now making a standalone DCT controller made specifically for BMW DCT transmissions. Just need to find or make an adapter plate.

So far the only downside I can think of is the weight penalty which is around 30 - 40kg over the manual trans I was considering so not insignificant.

Paddle shift would be nice!

I like the idea. I was actually looking into a DCT for my swap but probably will go with a sequential.

I'd love a sequential but this DCT is a quarter of the price.

My thoughts: If it fits, it sits.

What about adding a sequential shifter to a standard gated MT?

From what I can tell you still need to use the clutch and they are expensive.

I get it the price is right, and its decrease in shift time is great. I may still entertain the idea of a DCT from Tremec. I gotta price it out, and see specs on both.

From the research I have done so far a used DCT with about 40k miles on it will cost me as little as $1k USD. Then its another $1100 USD for the full adapter kit which has not been released yet so price may vary. Then another $1300 USD for the DCT controller.

Runner up option of a BMW ZF 5-speed manual works out at not that much cheaper, mostly because they were not common here so the trans needs to be imported. Still a great option though if you don't live in Aus.

Saving up for a few bits at the moment but that hasn't stopped me working on the car.

Something I have been thinking about for a while is pushrod suspension but I was just not sure it was something I could do. So I figured while I'm waiting I would make a full scale mock up and see if I could get my head around it.

The main reason for doing this is to design a rising rate suspension to help with aero loads. Version 1.0 was completed last night, below is the video

https://www.instagram.com/p/CBU5x_1AjT1/

This allows me to measure the wheel travel versus the shock travel. I then put the numbers in excel and I can plot a graph showing whether the design is regressive, linear or progressive.

Version 1.0 came out regressive and it is not using all of the shock travel. So by adjusting the angles on the bellcrank and the distances between holes I will work to getting it how I want.
