Looking good Colin, I'd be happy if I could paint as well as that

The front wings are the best of a bad bunch. You will note I haven't posted any photos of the passenger door..........

I'm going to have to have another go at that tomorrow.

looking great colin!
did you have any issues bleeding the brakes with the master cylinders being level if not below the height of the callipers?
i nearly went that way on mine but heard of bleeding issues and also long pedal caused by the fluid draining back to the master cylinder more easily, probably be fine but thought it worth mentioning in case you come across a brake issue

[lee303]

oh and if you do find you get a long pedal with the new setup, you can fit these in line to stop it happening

I can't comment on that as I haven't bled the brakes yet.

I must admit I hadn't considered the height, but plenty of race cars use floor mounted pedal boxes with direct reservoirs. Thanks for drawing my attention to it, if I get any problems it's certainly something to think about.

Thanks for that, I hope I don't have a problem as I have enough to get done to the car without having to order more bits, wait for them to arrive and then get them plumbed in and tested!

yeah like i say it may well be fine, but i know that quite a few of the prototypes run the residual pressure valves to get rid of the need to double pump the pedal, at least you wont be scratching your head if you do find a problem but can appreciate the hassle it may entail isn’t what you need right now!

Colin ~ depending on ride height you might want to put the RJ rod ends under rather than over on the knuckles.

Thanks.

We did all the geometry and corner weights yesterday, and the steering arms are perfectly flat with the TRE above the knuckle, and just a thin washer under the rose joint to prevent any binding up on metal to metal contact.

Straight out of the box the corner weights were within 2kg on the diagonals.

It was weighed without the exhaust system, doors, rear bumper or the rear side/tailgate windows.

And the total weight was..............drum roll............540kg.

I reckon those bits that need to be bolted back on will weigh 25-30kg, so my target weight of 570kg certainly seems to have been achieved.

I'll weigh it again once everything is back on the car just to be sure.

Once the split rims go on the front, and I get the lighter weight front brakes fitted, there should be another 10 to 15kg to come off the total. Happy.

That is a good result, all your pinching and stealing 100-200grams here and there have certainly added up without taking anything away from the overall car.
