chassis ordered

15 Apr 2011, 10:26pm
took a day off and went down to crediton today to order module1 :)

Didn't take any photos as I kind of forgot. The super size dogs would have made a good snap though if I had a wide angle lens big enough.

Some interesting developments worth noting:

- The front axle design has changed. Marlin have adopted a light weight alloy Rally Designs front axle which sits more vertical than the rear leaning BMW axle, This will mean buying a wilwood set of calipers to match (supplied). In my case I asked if I could go the old route of having the BMW strut chopped as I'd already referbed my calipers etc and they were happy to do this. It is worth bearing this in mind for future builds though. the new layout is much more tidy and in my chassis I will still get the sleeker general improvement of the general re-design so a future upgrade is not precluded. I'd have liked to have gone for the new set up but it would have added extra on my current budget.

- The M3 based car Mark is working on at the moment has some very nice small rear springs in it, about 10cm in diameter and 20cm high vs the much larger BMW springs. he hasn't settled on the correct ones yet as he needs to get the car on the ground to decide on the correct spring rate but once that is decided they will be a custom set designed specificaly for the sportster and supplied by Marlin. To adapt to the rear upper wishbone there will be a bolt-in adaptor to seat these springs


Need to concentrate on getting the remaining garage issues sorted now. still need to paint the floor etc and get some more storage in plus finish the really grotty bits of restoration. It's good to have finally got the order in and they promised delivery in around 4-5 weeks-ish which is sooner than I'd expected. not in any particular hurry though so if it moves out it'll just give me more time to get other jobs finished.

Great to hear another one will be under construction. Keep us posted (will have a build blog section on Madabout very soon)

It'll be interesting to see how the cycle wings evolve to attach to that.

This is the ali one:

I wonder if they'll try and use the same bolting holes that the caliper carrier uses...

They all do a steel one:

I went the same way as you and used the BMW struts and calipers. I think it would have worked out at an extra £600 at the time to go the Rally Designs and Wilwood route and I couldn't see what advantage that £600 gave me. Also, the BMW strut (E36) looks like a firm mounting arrangement for the wing stays where as I hadn't seen the solution based on the Rally Design set up.

That's the badger.

I didn't check the price with Mark as I knew it was going to add on pounds I don't have at this point. going by the £200 for the axles on the rally designs web site plus the cost of new calipers at around £130 each I think it will be much more than £600 now.

The main advantage is the unsprung weight. They do also look neater and less donor-y and it allows the suspension to have 0 castor. not sure if that will improve the weight of the non-powerered steering?

If I hadn't already gone down the full donor route but rather just buying in the separate parts + drive train from a scrappy I'd probably have considered it. They did confirm that the top wishbone and axle could be swapped out in future though suggested that it would be cheaper to just to buy some aftermarket calipers designed to fit an E36 if that was the main driver.
