Default IVA Application

Hi all,

I'm filling out my IVA application and there are one or two questions I'm not sure on so looking for some advice from recent successful builders.

1. Type of body - I've put 'Roadster'
2. Colour - I've put multi coloured and don't think they can argue with that
3. Max design road speed - The 325 E36 top speed was 146mph. I would not think either the car or occupants will be too happy at that speed but what's the best estimate to go with. My tyres are V rated so ok there (149mph) and the speedo goes to 150 but will this affect the brake test or is that just done on the weight?
4. Design Weights - Axle 1, Axle 2, gross, train, towable mass. I now know the actual kerb weights but that's not the same thing
5. Build evidence. I was going to submit the receipts for my donor plus modules 1-3. Maybe also a 4-5 photos of various stages (that really prove nothing)

My kerb weights (but 1/2 tank of fuel) came out as axle 1=402kg, axle 2 = 478 kg and total = 880kg. At some point in the past I wrote down 550, 700 and 1250 for the design weights but can't find any evidence of where I got that from.

Any advice on what others have entered and had no problems with is gratefully received.

I'm also after any other advice at this point. Things I'm a bit worried about
- self centering. I've set castor to max+ and have 2ish degrees neg camber. Toe is a bit on the vague side. The rear is what it is though I plan on reducing the currently rather extreme neg camber using the eccentric bolts. My turning circle is shocking due to my limiters but as I'm not driving to the test I can leave that till another day (I assume).
- Brake servo hose. Mine is silicone. My MOT man said he'd have no problem with it as it was all done up tight but was not sure if the IVA man would perceive a chaffing risk. What have others used, braided fuel hose?
- Coolant leak. my 0 pressure rad cap has a habit of spitting half a cup full of coolant out during warm up but I think this is because the seal is not well bedded in. The main system is on a 2 bar cap on the expansion tank and the one on the rad is there just to plug a hole that's not being used for its intended purpose. Once hot it settles down. If this happens on the test will I just get a raised eyebrow or be pointed to the door. If it was oil, fuel or brake fluid I know the answer, but a little coolant...
- front braided brake hoses. Mine float free between the chassis and caliper and are not clipped to the wishbone. I think this is actually less likely to chaff than forcing it to run in some sort of sleeve, but it's not my opinion that counts in this case

Thanks
Ian
