Rear axle boot
Re: Rear axle boot
he told me it was 50404.55
Re: Rear axle boot
From what I can find those are springs for the m42 318i. They won't lower the car as much as the right ones.

Re: Rear axle boot
I just did a quick search and it seems both 50404.55 and 50406 will work on the '87 325is. Now i'm thinking if ride quality will be F'd up if I have the 50406 in the front and 50404.44 in the rear.
Re: Rear axle boot
They will both work, but the 50404's were made for the lighter 318. Now that I think about it more those springs might actually make the car sit LOWER because they're designed for a lighter car. I thought I read someone else say they sit higher though. I'd just get the right ones all around if he's offering that.

Re: Rear axle boot
There is no difference in pretty much any parts between the 325i and 325is, so suspension, driveline, interior, etc will all be the same. The car will sit pretty much the same height with the 318 springs, but the rates are lower so the ride will be softer nominally. I'm sure you'll be fine with either springs.

Re: Rear axle boot
But you guys agree going with two different Springs is not a good idea.
Because the guy I was buying it from said he can't get me the other ones to complete the set.

Re: Rear axle boot
It's more about preference. Would you like a softer ride in the rear than in the front, or do you want it to be more equal? Some people prefer MUCH different rates in the front and rear.

Re: Rear axle boot
Traditionally the rear springs have a higher rate than the fronts. Having lower rates in the rear could cause some undesirable handling characteristics if you plan to do any track days or autox. I would pass personally, just because the dude seems shady to begin with. You can get H&R sets on the forums for under $200 almost any day of the week, just get a matched set so you don't have to guess.

Re: Rear axle boot
I am also passing on those springs. He said he also has some purple ones that drops about 2" but doesn't know the serial number yet.
So..we will see.

Re: Rear axle boot
No better color than purple! I think a 2" drop would be too much on these cars as a daily driver though. I scrape the shit out of my exhaust on speed bumps already with only 1.25".

Re: Rear axle boot
Color purple always gets me.
2" is a big drop especially with the original wheels.
I saw these on ebay and I'm a little tempted.

Re: Rear axle boot
The problem with drop springs is they lower the car without increasing the spring rates too much, so you get a lot of bounce which it where the pan cracking hits come from. My J-Stocks are really low, but with the high rates the car bottoms out less than it did with the H&R Race springs that had less drop.

Re: Rear axle boot
Good point, but do you ever drive over speed bumps? Even driving at 1mph I have to go over some speedbumps diagonally or I'll scrape exhaust.

Re: Rear axle boot
I would definitely require bigger wheels, if I go 2".
