Car hasn't even been rolled since the install







amazing camera skills

Thats interesting, the billyss dont bottom out until you tuck undersized tires?

This is no springs at all for comparison



318is is stock height lol





I might throw them on the 318 for a bit just to get some ride impressions

I know lol. I so wish I could drive it at that height front and rear. My exhaust wouldn't be very happy though

iirc from my earlier shock research bilstiens unlike their competetor Koni's are ride height sensitive. Meaning they have a "happy zone" in which they operate very well. if you ride them too low or too high, they will not perform as they should. So even if they are not actually bottoming out, they still may be out of their desired range.

this has been proven with the h&r setups. the normal h&r's when slammed all the way down ride terribly, and also is true when you raise up the h&r ultra ultra lows to their highest setting.

Koni's on the other hand will perform the same at any height unless they physically bottom out, and also do not have internal bump stops like the bilsteins

Thanks man! I notice on ebay they only list the 75/50 for 318. Is that what you got or there is 325 application as well?

[E30SPDFRK]

The company never returned my email about weather or not they have 325 springs as well. I bought the 318 ones as these will probably spend most of there time on mine.

My m30 is heavier than an m20 though, so if they work on my car they should be fine on yours.

I dont doubt it. Eventually i will probably swtich to a shorter shock, as i feel like i dont have much lower i can go

TBH gonna have to say my 60/50's look better then those:








This is with spring pads all around

[awestun]

His springs still haven't settled. What springs are those?

[E30SPDFRK]

I put my factory sized tires on today for s&g's and I am right about the same height as your front is. Your back end looks way lower, but that's because I have an early model. I measured a 30mm gap from the tire to the fender and the difference between early and late is about 35mm. Lets hope mine settle that low!
