    Hi guys, im fitting BK Racing 171 alloys to my E30 (17" alpina look-a-likes) with 215/40 R17 tyres. Id also like to lower the car. My question is how much to lower it? i want to keep the car practical as i use it daily, id just like to improve the appearance. I have an mtec2 body kit which i think will go well with the alpina's, i think the height of the car is going to be important to the over all look. If anyone has any pictures of their E30's with the same tyre/wheel setup id love to see and know how much they decided to lower by. I'd also appreciate any suggestions on how much to lower mine, again i want a practical ride with good looks, a good compromise. Cheers, Lee

    hi Lee

    I dont have any E30 pics of your alloys Im afraid but I would say from bitter experience, the lowest you want to go is

    40mm drop F and R


    bearing in mind I say that with standard alloy sizes.

    I think with 17's tbo you dont NEED to drop it!! because they fill the arches so much more, but even though they dont make springs this size I would say 20mm is an optimal drop so you can still make a speedbump without having a coronary

    You could get the springs chopped 20mm and do it that way, or buy uprated stock springs and get those chopped, along with some bilstein dampers. (Not Koni if you can avoid it)

    If you have to, then go 40mm lowered springs, but make sure youve got a gumshield and that you dont mind squeaks that werent there before when you go over bumps!

    My opinion is you're only too low when you take a snails home off it's back

    If you do it properly then the ride should not be affected too much. 40mm is more than low enough for your car on 17's any lower and you will have to add shortened shocks.

    I would NEVER advise anyone to cut springs, instead you can remove your springs and send them away to be custom modified.

    That's only if they haven't been secured into position though isn't it?

    I used to have several mates who chopped springs... One of them went over a bump to quick and the spring fell out of the front shock cup. Imagine having to try and put that back in on the side of the road.

    I'd hate to think of the consequences that could arise due to this sort of incident happening at speed on a busy road.

    You can have shortened springs,depends on the tester really.
    The rules are.....
    Shortened or lowered coil springs.
    Take care when jacking vehicles with shortened or lowered springs fitted. Provided the spring ends locate correctly when the vehicle is lowered into the normal running position, without assistance this is not a reason for rejection.

    Reasons for rejection.
    1. A coil spring
    a. incomplete,cracked or fractured
    b. worn or corroded so it's cross sectional area is reduced such that it is seriously weakened
    c. repaired by welding or damaged by excessive heat.
    2. A coil spring not correctly located.

    Some testers will have it on #2 or 1a, like mentioned it's all to do with whether it locates without assistance so if it's clamped in place and the ends are in the correct slots etc it will be fine

    Like Ronnie says

    If its done well and fits like the original (eg/ you cut it in the right place!)
    then you 'should' be ok

    This should be the trend to follow when carrying out any modification to your vehicle.

    Too many people out there take short cuts and are driving around in potential death traps.

    I would take the view that if it passes the mot then it's safe (on the day of testing)

    I personally would prefer to use the coilover set up in order to get the exact look I desire. The advantage with this option is obviously you can higher or lower to suit your driving requirements.
