BMW E30 Street/TimeAttack (DTM style control arms)

[Miuge]

Let's continue after a little break.

Made an inner fender for 650mm tire but it also allows me to use even bigger and wider tire if necessary:


Side panel's wheel gap also found it's shape. This 615mm diameter wheel looks a bit tiny with stretched tyre...


I had to photoshop a picture which demonstrates upcoming wheel setup

[Miuge]

Today's photo I'm going to take a fiberglass mold after finishing it with COUPLE of kilos of filler...

[Miuge]

It was a good day to weld some aluminium so I made a fuel surge tank:

[Miuge]

Intercooler water tank, capacity +10liters. Bosch water pump will be located right next to water tank, it pushes water to intercooler then through the radiator back to the tank:


Alu tanks pretty much completely welded:


Then we move on to something else...
Draw a rectangle:


..and cut it out. Radiator air outlet:


Spent few moments measuring M30 head:


Good fit, afterwards I decreased the port size a little bit. I think it's ready for cutting:

Looking awesome

[Miuge]

Thanks!

Last week I visited at a local paint store and bought 3liters of primer, days are getting warm enough that I can paint the car outdoors.


Yesterday I tested some kind of special grinding wheel which seemed to remove paint nicely


Aaand then I also made an intake flange model, I'll order both IN and EX flanges at the same time:

[Miuge]

Hmm, it seems that the chassis is getting ready for the primer! Last weekend we cleaned the rest of the chassis (excl. doorposts and the roof). Found just a couple of small rusty spots which I already fixed.
I'll post pictures by the end of the week

[Miuge]

The pics I promised, it was a great weather to paint outdoors, sunny, warm and no wind:

Nice Work!

[Miuge]

Thank you!

Last week I didn't have much time to spent at the garage, but I made a temporary solution to get the front wheel in right place


Then I was able to start work the front fenders:

[Miuge]

Front fender has a couple of functions; hot air comes out of the engine bay and wheel well from the back, also air from the front splitter/diffusor will be vented on top of the fender:

[Miuge]

No new updates lately, been working with the front fenders just a little bit and designed functional/imo good looking side skirts.. I'll try to get some plywood for the mockup this week.
Custom front control arms have been on pause, prototypes are pretty much ready and I have material and accessories for a couple of sets

I spent few moments with the sketch, this is how things should come out during winter:

[Miuge]

Got the first fully adjustable CrMo control arm prototype "assembled", missing a couple of bushing and a spacer. Complete kit weighs less than half of the orginal setup, but has the same rigidity.

There will be an upcoming contest at our facebook page where you might win one set for free, so make sure to like the page so you won't miss it
Control arm pricing will be published by the end of November.

Really nice work!

[Miuge]

Thanks Erik!

Finally had some time to realise side skirt mockup. I hope they don't look that block-like when finished with couple of details and corner radiuses Current wheels look sooo tiny, 650mm dia will look so much better without any tire strech.
Flat floor determined the skirt dimensions, floor will be about 20mm off the beams in front end with rubber mounts. Ride height I'm aiming is about 80mm.
