I installed the öhlins R&T, car no longer pulls to the right (short review)

Hey, Guys.

The kit is Worth every penny imo, the car had a strong pull to the right before , completely gone and i haven't even had the car aligned yet.
I have about an inch drop in the front and rear, i rebuilt my Ground Control camber plates to work with the 65mm ohlins springs instead of using the adapters to work with the stock upper hats.

I absolutely love the ride in town, better than the EDC's comfort mode, it's the valving that really helped the ride considering the ohlins has almost doubled the spring rate up front.

I'm running 550F/672R. Also no Noise, vibration, and harshness (NVH).

Thanks for reading!

Also big Thanks to Harold at HP AUTOSPORT for getting me the spring rates i wanted and the guys at Ground Control for getting me all the stuff i needed to rebuilt my camber plates.

Is your m4 equipped with ZCP?
Can you give a more detailed review of comfort level between stock and Ohlins?

What suspension were you running before? Are you running the same amount of camber? Very curious as to what may have been your source of right pull. I'm still chasing mine down.

It pulled to the right on the stock suspension with and without the camber plates. I had a few alignments done, didn't fix it.

The car is really a joy to drive now...you can let go the steering wheel and it goes straight.

The Öhlins kit rides much better, you really notice it on rough roads. It's better than BMW's EDC set to comfort mode.
No ZCP.

A bit off topic but did you get any noises from your GC camber kit ?

Did you adjust the caster compared to stock?
That's the only adjustment I have not made in my car.
I have the Dinan suspension and GC plates, car still pulling right.

Sorry to ask again. You mean Ohlins kit rides better than stock on rough roads even the spring rate is two times than stock ones?

The dampers is where it's at. High quality dampers will soak up most of the shocks, control the spring oscillations and offer an excellent ride quality even on higher rate springs.

We would love to see some photos of the installed product, especially the rear so every knows where to set the height adjuster for lower rate rear springs.

yes, this is the part I can't understand. Due to Ohlins kit has higher spring rate comparing with stock both front and rear.
Personally, my car is a 17 ZCP, I feel with 20 comp rims, the car is really upset on some roads in Toronto.
I really want to have a minor drop and improved handling over the stock ZCP, but I drive the three to four days a week, I also don't want to lose any comfort.

We supply lower rear rates in the 672 lb/in range to improve ride quality.

OP can you chime in more regarding to the ride quality?

The Ohlins do great on the small bumps despite the spring rates b cause of the DFV technology it uses.

The high springs become an issue on the larger bumps when the high rate springs rebound and the shocks have to stop that motion VERY QUICKLY. It's there on the upper end on the rebound stroke that the Ohlins get harsh.

Damping is great though, spot on and very controlled. I think lower spring rates and it will be amazing all around.

Just to add to the thread, I got new tires put on tonight, and in the process found out where the clicking sound was coming from.

The front perches were both loose.

Love hearing that this fixed it, but for the love of gawd, we should not have to install CO's to solve a tracking issue, no?

For the record, the more I drive the car, the more I think it's not an alignment issue. I honestly think it's something to do with the steering rack.

It's hard to explain, but every time I let go of the wheel it INSTANTLY moves a few degrees to the right. That's not alignment, but a steering issue.

And thinking back on how the car was great for the first couple hundred miles, but started getting worse and worse to the right and now it's come back and gotten worse makes me think it's something outside of alignment

but still UGH!

I've been playing with the settings, 20 clicks from full firm front and 23 clicks from full firm rear achieved the smoothest ride, with amazing handling still.
EDC is a waste of money!
