Suggestions on Smaller Diameter Front Springs

weehe126 · 07-03-2023, 08:05 AM

I recently installed M3 zhp springs, Koni yellows, millway camber plates and millway monoball front control arms. Love everything about the setup except that I can't get more than -1.6° camber before the spring rubs on the body. I'm at about 12-13mm out of 22mm on the camber plates. If I can get to 22mm I'll be happy.

With that said, does anyone know of any springs that are smaller diameter than stock springs but have the same or higher spring rate than the M3 zhp springs? I'm kicking myself that I didn't just do coilovers to start.

Does anyone have experience with the F80 H&R sport springs on a 340i? Visually they look like a smaller diameter and would have slightly higher spring rate than the zhp springs. I'll be asking H&R what the actual diameter is to compare.

Bump.

Ran into this exact same problem after installing my setup a couple months ago except used 034 Dynamic+ springs and didn't install monoball arms. Shop said they were only able to get -2.0 degrees camber from my millways and i'm currently experiencing rubbing on full lock in both directions.

Someone on the forum posted awhile ago about there Dinan spring/koni/millway combo getting more than 2 degrees if i'm not mistaken.

Based on the pictures and posts I've seen, the Dinan springs are probably wider than the stock.

Just heard back from H&R on the F80 sport springs. They are 144mm in diameter at the widest part. Stock M Sport springs are ~171mm. I still need to measure the M3 ZHP springs, but visually they are bigger than the m sport springs. Will be ordering the H&Rs and will report back.

Just installed the H&R M3 springs. Am now able to max out the camber plates. They are 1" smaller in outer diameter than the zhp springs. As expected it lowered the front a decent amount, they were 2" shorter than the zhp springs. Will get some pics up and see where they settle.
