this looks so good. Great work so far. Can't wait to see the next update. You are building a very cool, fun car.

Can hardly wait for a track session video with overlaid datalogging . . . yeah, I expect there will be a bit of 'sorting' involved.

Setting up the suspension is a big concern for me but it should come together eventually. I won't buy rear coilovers or build the front bellcranks until I know my corner weights though.

I'm really glad I made the inner control arm mounting points so adjustable, I've already moved the top inner mounts down a little to add some camber gain but I can see the lower mounts will probably need to be slid down a little too. I've got to measure everything again at some point and adjust it all to my original model I came up with in the software.

I have been working on the front end, trying to make the panels fit over the new wheels by trimming away metal and plastic from the front fenders and bumper.

This photo shows how low the car is and also that I have extended the wheelbase by 35mm by moving the front wheels forward.

After some trimming I could get the panels back on, you can see I need to remake the panels with a new shape.

I also had to seek some clarification on the rules as one section said I could cut away any metal necessary for bump clearance and another section said I could only make changes to the shock towers solely for suspension geometry changes.

After getting the go-ahead from the technical director I did the minimum amount of trimming to the strut towers so the tyres would no longer make contact.

I have also been trimming away some metal around the wheel wells to help with air evacuation, I post some photos of that once its done.

Looks like I have found a workaround for this strange thing that has been happening with my photos.

For some reason it kept going to some website http://dereferer.org/

I've been in lockdown the past few weeks and it probably won't end any time soon. Luckily this has given me plenty of extra time working on the car.

Most of the work has been around getting all the front end panels mounted onto the car. I bought some 16mm x 1.2mm 4130 chromoly tube and a very cheap manual bender from ebay. The bender snapped during the first bend but I was able to modify it to mount in my vice and now it works surprisingly well.

The tube structure I'm building is very light and will be removable by taking out several bolts. First step was to make a rear mount on the chassis.

This is how all that turned out, one on each side.

Then it was just a matter of bending some tube and making some tabs to hold the fenders in place.

//i.imgur.com/O21jXLg.jpg?1

The whole thing is rather basic but it is surprisingly sturdy.

This is it after finishing both fender mounts. More tube which I have already bent up will continue around the front and attach to the top of the bumper. I have left that bit off for now and started work on the main reinforcements to the front chassis rails.

This is my proposed tube routing to reinforce the front frame rails. Lots of measuring and clearance checks to arrive at this point.
What do you guys think?

Looking really good now! I also didn't know you had an instagram. Following you now.

The front wheels being moved forward screams to have some proper pieces made to help get air out of the wheel wells!

I was playing around with the bodywork today, nothing serious, just kicking around some ideas.

Vents on the rear side of the fenders will help a great deal with evacuating air from the wheel wells.

I was thinking vents more like a 911 GT1 or the WRC style that roll into the wheel well itself.
The vanes like on the JGTC BRZ would be tricky copy in composite (for me) and a lot of CFD to optimally aim. Don't forget they also carry off the back of the fender like a shelf towards the mirror.

I intend to leave the back of the fender completely open, I just made the mdf run all the way down so it sits level.

Work has begun on bringing the strength back into the front end, much more to come.

Yeah, saw that on my feed. Just as satisfying to see it again
