So next on the list was the roll cage work. Once I had the seats i dropped them around to AGI and we mocked up my driving position. Once they had some measurements they marked the positioning for the main hoop and the building could begin.
Because i'm a bit long in leg, i realised the seat back was behind the B-pillar, so adam grabbed the second Velo and put it in the cabin. Seems that the seats fit side-by-side behind the b-pillar by a bee's dick, but that's all that is needed!
As you can see in the pictures below they were welding bases onto the car with captive nuts, then bolting the cage will bolt directly to those bases. This was done due to the age of the metal the cage is bolting to.
The idea is to have the whole cage removable by one, and the front half as it will be taken out for road duties. The rear stays mount to near the top of the rear firewall to maintain the required 30 degrees from the main hoop, they will then bolt to the top of the main hoop. Speaking of, the main hoop is on a slight rearward angle to allow me some more backward room with the seat angle, pretty nifty. these blokes have done a cage or two before...

Old mate Richard came over on the weekend and brought a little gift. a Weber 45DCOE
this is how the passengers seat sits when the drivers is in a more-or-less perfect spot to come forward on rails/slides. It will have to come across slightly, but i think we can make it work
drivers front on, the rails will angle up so the wing will rise as it comes forward to miss the b-pillar
Looking at the passenger seat as close to the b-pillar as possible
Said Weber 45DCOE, roughly setup for a 1408

and you're all up to date now... thats how the mini sits/stands.
Next up is fabricating the rear beam and sorting the suspension out. We're running with the good old camber pin idea, similar to below, on the trailing arms so we can have camber adjustment, and we'll be modifying the internal mounts so we have toe adjustment. It's simple so should be fool proof (i.e. i can use it)

Interested to see how the OCD goes when you find the steering wheel sitting 20mm off centre from the driver... My old AU falcon was like that from factory. Worst car problem ever and I couldn't believe it was factory like that...

i might duck out and see the centre of this seat compared to the centre of the old mount holes. Would be interesting.
I do understand there will be compromises in the car. the most obvious currently is that i have shoved the passenger seat over so the drivers is in the best possible position. Its not symmetrical, but it will be a drivers car

Seems from measurements the new seat has actually lined up better with where the steering wheel *should* be.

So sent this drawing off to be fabricated today. Should be done sometime next week. Its the base of the new rear suspension, the trailing arms mount to it, doing away with the subframe... well, as long as the engineer approves of it
And apoke to Carl @ Force Racing about some 3-piece 10x7 wheels. He has a new mesh design hopefully finished at the machinist today. ExcitementLast edited by MkI; 10-13-2015, 02:49 AM.

In good news Carls happy to split the set of wheels into two pairs. Which will save me a few hundred
I will be getting the CAMS paperwork for the rollcage today, along with (hopefully) the delivery from Velo that was the seat mounts and slide.
I had a beam fabricated but there were two issues, firstly i made the design 4mm too short - derp! - , and secondly the mounting holes on one end weren't drilled to plan... so i'll get them to do it again and ensure they at least make it to plan. It might be harsh but i gave them a good clear drawing with every dimension and they made one end perfectly and the other is just a mess.
So hopefully version 2 works

Oh and just sorted the beam out this arvo. Popped past the fabricators at lunch and chatted. I'll drop the beam off tomorrow and they'll weld the holes, clean them up and re-drill. The rest of the beam seemed to fit so well its a shame to chuck it. Especially as the engineer could **** the idea and if i had a second made then 2 would be trash.
I also missed my delivery of seat mounts and slide, so have to work something out there. Shame they only deliver in my area at roughly 1:30pm
