Say gang, is there anyone here who has experienced both the ATRs and Ohlins, and can speak to comparison? the difference is in ride quality, whether the extra money for Ohlins is worth it, etc.? Going through past threads, it seems like the ATRs are more than adequate. My plan is to stick with the factory rear Spax shocks and just changes out the front. I know the Ohlins can change the stance a bit in front, so I wonder if it's wise to swap out front without changing rear? Given that most of my driving is on country backroads 50 to 60 mile jaunts, (no competitive racing) I think the ATRs will be good enough.

No opinion on either. BUT, instead of concentrating on the front and messing with the stance and steering, I would give some serious thought to investing in the rear. Every time I've hit something on the rear wheel that shock goes right to the spine. The pivot point for the wheel is just inches from your hip. What happens on the front end does not affect the whole bod but the rear can ruin your back and your day.


What's your mileage? Who cares. Is it practical? See #1. What happens when it rains? You get wet.

Also think about the rear shocks reducing the stress on the fuel tanks and their mounts. Cracked fuel tank seem to be a theme too.

Go both front and rear and adjust the ride height the way you want it with the thought in mind that the stiffer the ride the more shock to the frame and everything else in the vehicle.

Can't comment on ATR versus Ohlins beyond saying that the Ohlins are very good.
Regarding front/rear; if you are going for only one end, get the good ones on the front. The standard back shocks are a lot closer to adequate than the fronts and you'll feel the benefit more than going the other way. My guess is that it's a combination of most of the weight being on the front and probably the geometry being more sensitive to damping settings.
I did run the Spax adjustables on the back for a while and they were pretty good, not as good as the Ohlins but the big difference with the Ohlins was at the front.

Ditto what Calum said. Ohlins over stock Spax up front is night and day. I ran only the fronts for a while. After the rears were installed, I'd have to say that 90% of the 'seat of the pants' improvement is still up front.

Anyone with the ATRs want to comment here? Even judging from the older Ohlins thread vs the ATR thread, seems like a lot more people are running the Ohlins than the ATR shocks.

Now that we can't source the Ohlins from Ohlins US, it looks like our only option is to source custom shocks for the M3W from friendly sources over the pond.

Power corrupts. So my M3W is corrupting absolutely no one.

I had the Spax Adjustables on my last car and the Ohlins on the new one. The new car also has the Empire kit. My new car doesn’t understeer hardly at all whereas the old one really did and I much prefer the suspension on the new car. Definitely worth the money, I would say.

My car is fitted with ATR's all round and I am very happy with the set up. Not sure how available ATR's are in the USA, or even if Ohlins are available now from what you say but I don't think there is a whole lot of difference in their performance having driven M3W's fitted with both. As others have said, the fronts seem to make a bigger difference than the rears, so if you are only doing one end, make it the front. You could maybe fit the cheaper but still good adjustable Spax to the rear to sort out any ride hight problems? The standard Spax do tend to droop over time.

I think the reason for more running the Ohlins was their availability in the USA and in the UK they are available as an option fit from new from Krazy Horse. Those that have fitted their own shocks, at least in the UK, are more evenly numbered.

These are the UK suppliers of Ohlins who import them from Ohlins Sweden, all the dealers get them from here.

Thanks for all the comments, guys. And the patience to walk through these old topics. Even though I've owned the car a year, I still feel like a newbie. I am hearing that the ATRs are good but that the Ohlins are the way to go if you can afford them. These days however, it's more a question of "well at least you can buy the part...."

I have a quote of £577.08 each for the Ohlins (before shipping) which--if available, and "plug and play" (they come with spacers etc), seems expensive but something I will appreciate paying for over time. The ATRs are £700 for a pair before shipping. I have been dealing with UK shops via email and the sales reps are very helpful.

As for rear: anything that will save the fuel tanks!

Longer story: my bump stops disintegrated on the original 2012 front Spax shocks. And a jolt to the front end will transfer all that energy straight to chassis. I bought a pair of unused Spax shocks from an owner of a newer mog (2017 I want to say) for 50 bucks (I paid more to have them sent to me!). These have more miles on them but look in decent shape. I notice that the newer Spax shocks (post first gen 2012-14) came with a plastic tube cover over the top end of the shock so that the bump stop is not exposed to elements. On the used ones I bought, when I tilt it up and down I hear a little "click" under that tube. I think that is the bump stop that travels free on shaft (but at least it's there....I think?). Anyway, a new set of adjustable shocks up front will give something to play with when the snow melts this spring.

I'm leaning toward Ohlins in front (that is, the ones made for Yamaha: part number "YA 009 Yamaha FZ 1").
