    Right then, before I get 30 replies slagging it off, I know it's not the best/safest way of lowering a BMW.

    I'm racing a BMW E36 328i, in the Practical Performance Car £999 Challenge. Which is on Friday, I've striped the interior out yesterday and the car has raised up nearly 3 inches on the suspension. So my only real option is to cut the springs, unless I can get some lowering springs on Monday from somewhere, and I do mean I need them in my hands on Monday, not bought on Monday and wait for delivery, I haven't got that much time.

    The car is only being used for the £999 challenge, then it is being broken, so I can use the engine and box in something else.

    I know I can cut the front springs and use lock wire to secure them in, but has anyone know of the same method being used on the rear "pigtail" springs?

    If not, can anyone give me any sensible suggestions on how I can lower the rear?

    I need to drop it roughly 4 inches, if possible.

    4 Inches , you're going to struggle there mate even with coilovers and I think you know yourself that cutting springs is not the way forward especially if you're racing. Have you tried Roadrunner Motorsport? They're this side of Nottingham so you could nip over on Monday.

    I guess you could cut the rears, but those are the ones that are more likely to drop down and unhook themselves from the rounded spike bit from the car.

    cutting the rears down that much may affect the performance of the dampers travel ??

    i guess if you cut the springs down you could weld a tube to the radius arm centrally to the spring to keep it in place.

    I want to drop a total of 4 inches from where they are now, which is rough 2.5-3 inches higher than standard, due to the weight loss.
    So, it's only really a 1-2 inch drop from the standard ride height.
    The headache I have is, even lowering springs might be too high, because I've lost 250-300KGs out of the car.

    I think I might give roadrunner a call in the morning. Cheers for that.

    I understand your predicament mate but you're going to have to go down the motorsport route which is going to involve a complete kit rather than just springs. Roadrunner should be able to help, good luck and let us know how you go.

    if youve lost a few hundred kg then you could use springs of a lighter car e.g the 316 if they fit that is.

    It's not strictly "motorsport", it's getting thrashed for 1 day.
    It's doing 6 drag runs, and 6 go's round the "handling course" (a course of cones to drive round), then, after the weekend, it's being broken for parts.

    So, I want to spend as little as possible, seeing as, whatever I buy will be on eBay within the next 14 days. It seems a little pointless spending hundreds of pounds on a suspension set-up, only to have somebody buy it off you for half what you paid a week later.
    That's why I'm thinking of cutting the springs.

    Right then, I've had a thought today, after ringing round and not being able to get a set of springs until Friday at the earliest.

    What do you guys think to me clamping 2 coils together on the rear springs?
    I was thinking of using heavy duty steel cable clamps, like what you use to make the end on a winch cable.

    What do you think?

    You'd have the same seating problem as cutting the springs.
