I'm new to the single seater maintenance procedures, and i can't figure where the best jacking point is at the rear of the car? :o

What you need is a quick lift like this one.

I've got one of those. The only question is where should I stuff it? (Answers on toilet paper please.)

Seriously though, I have wondered, as single seaters don't have "jacking points". So far I've figured that, assuming the (Hewland?) gearbox is firmly attached to the engine, then you can put the jack in anywhere.

Unfortunately i haven't got a quick lift yet, i'm using a low entry jack and i don't have a hewland box either! :(

Assuming a MC engined car, then usually the rear cross member of the chassis or even under the centre of the car from the side/front again picking up a chassis member (using a Quick lift).

Not really critical, just avoid pinching brake lines or the suspension movement ect. and def. not on the engine sump.

It is common to have a jacking post protruding down through the undertray if fitted.

Quick lifts are a must-have. Making DIY is dead easy if you have the dimensions - the only difficulty is giving them without pencil & paper.

Not having a Hewland, I'd suggest the sump (with a bit of padding). After all, these creations are featherweight - but best wait for a BEC person for really useful advice.

Oops - sounds like the sump was bad advice - still I reckoned it was a safer bet than the jacking points on my Fulvia:)

The sump on the BEC would probably take the weight to lift the car, however they are very easy to damage and warp could easily cause oil leaks round the gasket.

In general engine mounts are designed to hold the engine down, jacking a car up on the sump is attempting to pull the engine up out of the car.

I'm sure I can do one cheaper - plenty of toilet rolls & sticky-backed plastic left over from Christmas:)
