E28 Coilover suspension DIY (in progress)

[5Toes]

How does one know if the spring collars will fit our strut tubes..? or do you just make an adapter to weld on that is the right size?

I am very intested in this!

You grind down the stock strut collar and just leave a bit there. Or you can get a donut to put around the tube and weld it on.

Hmm this is very very good info. So I assume the ebay honda coilover sleeves fit fine on the E28 strut bodies?

Also, do you have pics of the process?

Use a flapper wheel on a grinder to clearance the top of the strut so the sleeve fits tight. It will want to go onto it without this but it hangs up. I would not recommend using a grinder wheel as you may wind up taking to much off.

So basically honda covic strut tubes are the same circumference/diameter as BMW ones?

That would be a good deduction to take from this.

Do it mang!! I should have taken you for a ride in my e24 when you were down here. It would have you sold. We also finished up that e30 in the garage with the same coil setup, just g60's in the front and camaro gas-a-just in the rear and hot damn does that thing ride good!!!!!!!!!! I am hopefully gonna have the e21 completed this week with the same concept.

So would billy sports be insufficient damping for these honda coilovers?

They would be more than adequate.

The picture here is a bit dark but you can see where we are grinding down the top of the strut tube with a flapper disk and where the spring perch has been cut down for the collar to rest.

more pics?

And note, this works for EVERYTHING. They are all the same size diameter. E12 based stuff e28 based, and e30 based too. Shit, even E3s are the same. Everything should fit to drop these motherfuckers to the frame.

Thats all I have right now. I will be pulling it down in a few weeks to put in the custom valved billy struts and will get more pics then. I will also be doing my e21 this week and it is the same concept and will take more detailed pictures then.

I used e30 strut inserts but only bc I got such a good deal on them. Anything you can use for an e03 i.e. g60, ix, mr2 rears, etc. will work as well. Just add 1/2" to 3/4" over the difference they would be in an e30.
