Ohlins R&T V2 vs HKS Hipermax IV GT
 

I've been eyeing some coilovers for a while and I've decided that it's down to Ohlins and HKS. So just wondering about peoples opinions about them and if people have used both before and can make comparison between the two.
My car is going to be set up for mostly daily driving with the occasional track day here and there. Thanks.

Imho for R&T V2 MP21 imho worth considering fitting them with optional 50/50 N/mm springs, as default of 40/30 might turn out way too soft, if track use is considered too.

The Ohlins with camber plates are going to be like twice the price of the HKS. I have read the Ohlins can't go as low as most other coilovers for these cars and I believe the endlink brackets are not in the standard position. The Ohlins dampers are really good, though. The HKS have become really popular lately but I have not seen them properly compared to other options on the market.

I have both Ohlins and HKS Hypermax IV GT though on different cars/platforms.

I would only recommend the HKS IVGT if your doing less than 1-2 track days in a year and the car is a daily driver. But, HKS offers the Hypermax IV SP for track use for a good reason. If you do a fair share of performance driving the Ohlins Road AND TRACK will pay for themselves in smiles. The IVGT can absolutely be used on the track but, once you start to adjust it up your going to notice a bit more trade off you wouldn't with the Ohlins.

Pros for the HKS HPIV GT
-Half price.
-Include camber plates
-Longer Service/Rebuild Intervals

Pros for the Ohlins Mi20
-A much better ride at both ends of adjustment
-DFV's ability to soak up potholes and bumps is a huge plus
-Big USA location making rebuilds a bit faster. (I do believe HKS now too has a usa location)


That being said I've never regretted either coilover. I don't kid myself and call my fatass EvoX a track car. So having the extra $1200 to spend elsewhere on the car to improve my car's quality of life (read more hersepwrs) was well worth it. And on my BRZ ts, I could never forgive myself for putting anything but, a great coilover on the car that actually an improvement over the factory tuned sti suspension.

Thanks for the good info. I'm probably be going to get the ohlins then in that case seeing as it's better to just get the right ones from the get go. How is adjusting the alignment with the coilovers on?

No experience with the HKS setup, but love my Ohlins for driving around town and the occasional autox. Shop had no issue adjusting alignment to my requested specs.

On the Ohlins I assume? Same as factory adjustment if you reuse the top front strut mounts. I did not swap mine over and instead I went with Raceseng cascam adjustable plates from ft86 speed factory. They have an option specifically for the Ohlins Road and Track coilovers.

Oh the irony of this thread. I was actually looking at these as well! Good info

I love my ohlins, i currently have the 5k spring set, they are nice and smooth when dampening is turned down low, and its nice for autox too.

However, i was using both front and rear vorshlag tophats, and i couldnt really lower the car the way i wanted, i ran out of adjustment in the rear, i really wanted to go another half inch in the rear or so

at some point im going to get the 1 inch raceseng rear tophats

and revalve to 7k springs.

Also SPL endlinks are too big in diameter to work with mounting location for the front, i am actually going to order hotchkis at somepoint this week

We ran the Ohlins on our first shop BRZ, first with the (at the time) standard 6 kg/mm springs than swapped to 8 kg/mm springs. Great valving. Couple of little details that aren't great that have been mentioned. The narrow height adjustment range is one of them.

We do still sell them! With the 5 kg/mm springs, they're a pretty good street set up.

@Racecomp Engineering Can you comment on the new SUU MP22 versions? What type of changes have been made to valving etc. versus the previous SUS MP21? Do the new SUU MP22 versions include top mounts?

I feel like they release a new revision every year. The USA Ohlins site also has a product section for their new "Dedicated" series but as of yet it's only Porsche and BMW applications. We know they developed a set for this platform based on a user that posted it but he's gone MIA (couldn't have chosen a worse development/beta tester).

All of the changes over the years has been frustrating. Some of those changes have been welcome while other's have been steps backward.

Top mounts are now optional at extra cost, which IMO is a good way to do things. It makes sense for those interested in a street oriented coilover...OEM mounts work well for that and that's where these coilovers have shifted focus to over the years. But it's also good for those that want a different camber plate with more features and maybe a more robust spherical bearing than the kind of standard type camber plate that comes on the Ohlins coilovers.

The latest sets come with the 5 kg/mm front and rear spring set up right now. We make sure to specify that at this point. The coilovers are valved appropriately for those springs and it is quite good. We were not really into the super soft set up and we have not tried the Ohlins "dedicated" set up. We have done some custom valved track set ups in the past with some success.

SUU MP22? Looks like recent addition (all previous kits were prefixed SUS). Also MP22.
I wonder what might changes be. So far more or less get what differences are between previous versions of MI20, MP20, MP21. Would appreciate for someone to post what's new in MP22.

I share your frustration from a buyers perspective as well.

I would like to run some aggressive 200TW or less tires (RE71r/A052) on these and I want to make sure the 5/5k spring rates will support that while the car still functions as a daily driver with the occasional track day.

I would also like to know if the valving on these dampers support 6k/6k or 7k/7k spring rates or would that be really pushing them beyond their intended use?

See above for Racecomp's reply.

So, RCE with "latest sets" spoke about MP22, not MP21? So "new" - 5kg/mm springs, that were optional choice for MP21, now default? Or it's "We make sure to specify that at this point" - that is still option one needs to ask for when ordering?
AFAIK
MI20: 6kg square & included camberplates in set
MP20: "new" with 4kg front, 3kg rear, camberplates became optional
MP21: should be same as MP20, but TUV certified and with extra rubber seats for NVH (though according one MP21 manual seems that defaults might be not 4/3, but 4 square, and funny, but recommended spring preload also differs even for front with same rates.). And one could optionally order with 5kg square rates.
MP22: 5kg square by default, or not?

Seems PITA to hunt for specs that simply should be listed in product description page or linked docs on manufacturer website.

RayRay88: i recall seeing someone saying that usually good coilover valving should be able to accomodate +/-30% spring rate change. But i don't know for sure, if MP2* shocks still have same valving as MI20 had or not, saw contradicting info on that. If track on sticky tires is priority, imho custom valving might be better option. Or something like these BTO ones with 9/7 rates :).

Where is the irony?

They removed the included top mount parts> lowered the spring rates from 6/6 to 4/3 > readjusted the valving again and then added rubber spring seats.

Because they've changed so much, we just always specify exactly what we want.

With those tires I would recommend stiffer rates than 5k/5k but they'll still work well. The dampers will easily support 6k/6k. They'll support 7k/7k fine but that might be close to their limit.

Just remember their shift to more of the road side of the road&track equation. Totally fine for occasional track days. Great coilovers, just a little less flexible than they could be in certain ways.

HKS HIPERMAX S is the best

Last post = Over two years ago.
Don't add anything useful at all.

You dumb or something?
