Coilover Advice Needed!

Post by adnan.exe » Tue May 14, 2024 2:47 am

My Stance+ coilovers have recently just packed up.

Due to this, I have decided now would be a great time to upgrade to the BC Racing Coilovers.

What are your opinions on BC and if anyone has them on an E85 please let me know what spring rate you went for (I'm lost).

I daily drive my car and would love it to be softer over some of the very harsh potholes. A fast road setup is what I'm looking for.

Thanks!

You won't go wrong with the recommended spring rates of 5kgs F/8 kgs R.

I run BCs, and they are firm even on the softest setting with the recommended spring rates. But they have absolutely transformed the way the car feels.

I haven't yet bought them, but am planning to buy and install BC coilovers in the next few months. The recommended spring rates now are 5.5kgs F and 9kgs R. I will be going for custom spring rates of either 7/9 or 8/10, but will make a snap decision when I order :P

Good news I found out about the BC coilovers is that now by default they have a recessed top mount (like the image below) so that you can get full camber adjustment without the small adjustment bolts hitting the strut tower.

Thanks for all the replies! I'm going to be ordering some BC coilovers now. I called and they recommended the 5/8kg/mm just like you suggested. So that's what I will be going for.

Thanks again!

I think 5/8 will be fine, but if you want to make changes later you can buy replacement springs from BC. You can go +/- 2 kgs on spring rate, keeping the same dampers.

Thats great! How do I set them up so that they are even? just measure everything?

Measure first before installing, so that ride height is even left to right. Then after they're installed and you've drive 200-300 miles to let them settle, measure again. Don't worry about up to 6-7mm variance left to right - that's normal. If you need to adjust, it's easy to do in situ (it will be obvious how to once you install).

Appreciate it thank you. Should I try and match the current coilover length to get a similar ride height?

Fitted BCs just over a month ago. Went for 10K front - 12K rear on my daily Z4 which I also track. Front is as low as possible (normal BC BRs, not extreme low) and rear sits 1/4" above that for 1/4" rake. I haven't messed around with the dampening adjustment so far. Just kept it at 16 clicks. My back was hurting for the first 2 days (I also have a bucket seat) going from blown oem to these. Also occasionally hurts after long mountain runs on very bumpy roads. On road trips, I have easily done 2+ hours with my current setup. I think if I turn the dampening down to 8 clicks it would be perfect for the street, but I can't be bothered :rofl: Just also keep in mind that I am on the younger side (19), so my level of comfort might be different :D

Thanks for the input! I've gone for the recommnded spring set up as I've heard a lot of good things and springs are cheap to swap out I think Ill start out at 16 clicks also!

I bought them as I thought it was the cause of my sticky steering but I've looked more into it and I think it's related to the electric motor for the power steering, I'm going to give turning the motor ago :/
