Oooh, not done that before!

That's the first time I've managed an endo in a car before :eek:

Car is a 1978 Saab 99 Turbo, but with no interior from just behind the front seats (apart from the spare wheel). It's stripped out so I can route the cables for moving the battery to the boot. It has about 2 or 3 gallons of fuel left in the tank if that. Brakes are standard apart from goodridge hoses and silicone (DOT 5) fluid. I stiffened the rear suspension up a little recently which may have contributed...

Was coming home from work and having a bit of fun, me and a passenger. Stomped on the brakes coming up to a roundabout at about 70, and felt the front dive a little (I think I need to stiffen the front shocks a bit now!) and then the back felt very light and then a brief skid sound as it went down again. I do believe I had the rear wheels off the ground

So for those who think silicone fluid is rubbish, I say nay!

I look at it this way...AP racing do not recommend it's use, who am I to argue?

Hmm, who'd like to volunteer to drive behind me while I do it?

Make sure you use a modern car, I wouldn't want mine damaged when you pile into the back of it

Maybe AP racing don't reccomend it because it's not suitable for racing? Similar to DOT 4 in that respect... It is however perfectly useable for hard driving and trackdays. Not suitable for ABS though.

And anyway, I'm sure Burger King don't recommend you eat McDonalds - because they don't make it

With no weight in the rear the bias ratio will be wrong and the rears will have too much braking. This will cause them to lock. There is no way tyres on the front have enough grip to allow the rear end to lift.

Silicone brake fluid is also not a road fluid.

If it was just the rear wheels locking up the skidding would have occured when the rear was lifting, not when it went down again.

Reminds me of a kid going "how high, how high? I rekon that bunny hop was about 3 inches" straigning to look backwards when doing it whist all his mates are going :rolleyes:

watching him flex his tyre walls slightly.
