Ohlins R&T Coilovers with Swift Springs!

[SBD47]

Yes. The softest setting.I have a 7 seater model Y. It’s basically a family car. We don’t like to feel the road imperfections, just smooth ride overall. The road and track kit is still too hard in the rear. I guess I should pay extra to get the redwood one or mpp setup

If that is your application and desires, I’m not sure why you would’ve chosen this kit. It’s literally one of the sportiest/stiffest kits available. There are multiple better options for your use case. Live and learn. I would either order a softer set of Swift springs or remove the kit altogether and replace with MPP Comforts.

Just a thought…If you haven’t already, you could try adjusting your rears all the way “stiff” and take the car for a drive to feel the suspension. Then adjust the rears all the way “soft” and take the car for another drive to confirm that you are indeed adjusting from the right direction. Is it possible you are actually adjusting the rear stiffer, instead of softer? Wouldn’t be the first time someone did that with this kit.

@tm1v2 I have a road and track kit installed by your shop. It’s set at stock height.Would it be possible to put the oem rear springs back for a soft ride? I think the front springs works fine but the rear is a bit too stiff. I have them set at 20/20 for front and back now.

@hek8560 Umm that's kinda scary cause I don't have a shop! Wrong auto-complete on the @ username?

I heard it will be very comfortable (YouTube) and I didn’t do my research. I should have went mpp and it is almost same price.

Maybe you were looking at a review of the Redwood Motorsports GT coilovers? Those are the smoothest, most comfortable Model 3 suspension I've experienced. The pricier version is based on custom Öhlins DFV, and they just released a much cheaper version that isn't Öhlins based but is otherwise the same. That be version is the one I got a ride in and it was real smooth. (I'm told the Öhlins version is even better but I haven't experienced it myself.)

Yet. I think so. I am completely new to the the suspension brand. I simply couldn’t afford another suspension kit. I might just buy the swift springs and replace it myself. If I only change the springs, do I need to adjust the preload or length or the current shock? If it is plug and play then I might have a shop to do it.

If you still on the original R&T springs then I suggest you swap them out to 8kg front and 9kg rear before you swapping out the whole kits again. I did that and the result is day and night.

Is it DIY possible? Will it drop the car height due to softer springs?

Possibly if you have the right tools. It will drop by 15-20mm

Quick update:
Swaped out the springs for Rt kit for my model Y, and the car is so much smooth on small bumps and small road imperfections. No major difference on the wave road and big bumps.
However, the Y is lowered more than I expected. About three finger gap. Any way we can raise up the ride height for both front and rear?

Adjust the preload so you don't bottom out easily with softer springs. Thats what I did.

Here's a picture of a failed rear strut mount, a customer had a set of the 8/9K Swift springs installed on his Ohlins kit (Model Y, customer provided kit). The suspension bottomed out on a bump and pressed the bushing right through the mount. We obtained a new set of mounts replaced the failed mounts/reinstalled the original Ohlins springs for him.

Understand this is a model 3 thread, but these shouldn't be used on a Y and wanted to share with the forum. Not pointing fingers or looking for someone to blame.

Can you clarify what you mean shouldn't be used on a Y?

 

[tom @ eas]

The Swift Spring rates recommended are wrong for Model Y, which is much heavier in weight compared to Model 3. Suspension bottoming out caused the rear upper shock mounts to fail prematurely.

Can the ride height be adjusted without having to uninstall the front coilovers (Ohlins R&T)?

I would like to lower the car the proper way (use ride height adjuster vs preload). I'm not sure if there is enough space to turn the forks to accomplish this. I can potentially see the axle getting in the way. Will there be enough room if the spindle/knuckle is unbolted from the FUCA?

Also, the general Ohlins manual states one (full?) turn equates to about 2mm in height adjustment. Is this true for the M3P?

 

[B4dtzM4ru]

To increase the front ride height you'd want to increase the 245 distance and keep the 198 distance the same. In other words, increase the distance between the height adjuster and spring preload adjuster.

I've found the easiest way to do this is to loosen the height adjuster (rotate towards the right). Then turn the small locknut underneath the spring preload adjuster also to the right. Because the locknut and the spring preload adjuster are tight to one another, this will actually lengthen the damper without changing your preload!

While doing this you can also push up on the billet to take tension off the threads.

I just reread this after posting my question. So it looks like I don't have to unbolt anything and just loosen the height adjust ring and turn the preload ring (left in my case)? The upper part of the shock is free to rotate without affecting preload?

Am I understanding this correctly?

That's not exactly true. Ohlins had a bit of an oversight with their kit... the stock bumpstop (front and rear) engages the metal portion of the top hat. The Ohlins Road and Track, as well as our Redwood Ohlins GT/Perf Sport, and FPX all have their own internal bump stop, and hard mount the shock to the top hat. That would be fine with the correct design for a "bump stop limiter" which we include on our kits - but this was an oversight on the Swedish designed Road and Track version.

We sell the bump stop limiter kits separately here on our website to work with the R&T kits, and they are *included* with our Redwood Designed Ohlins kits, and FPX kits, or if you purchase an Ohlins R&T kit from us we throw them in complimentary to prevent this problem.

I'm putting these on my MYP and the stock R&T system is NOT what you want. Reach out to the Redwood guys if you want a kit that fits without trouble and has far more adjustable range. First of all the front spring has coil bind with no preload. This gives you no adjustment other that shock length that kills stroke. The rear only has about 5mm of spring adjustment and mandatory 15-20mm drop.

I picked the 7/11 switch springs to give me stock 165mm pack clearance with about 10mm of range to corner balance the car. This also gives a perfect 15% flat ride and matches the McLaren f1 frequency range.

Pack clearance should be 155mm. Stock MYP is 157.
