KYB LOWFER Sport Plus Review

:
2024 CX-5 2.5T
TLDR: Improved body control, sharper handling, and smoother ride. Spring/Shock combo ~$750 shipped to my door from Japan.

I purchased my 24' CX-5 this past April and have loved the look and performance of the vehicle except for one thing. The rear right height has always irked me. I mean you can fit a soda can in that wheel gap. I decided to bite the bullet and lower the vehicle a modest amount as I wasn't too interested in lower the rear subframe to install the RCA even though I have done this in the past. So...the search was on for subtle lowering springs.

After scouring the net for a longer than I'd like to admit, I settled AutoExe 30mm lowering springs.

Aaaannnnnd proceeded to no even use them. lol They are for sale btw.

After searching a bit more, and finding systems from Blitz and Tein (I'm an import tuner guy) I stumbled on a suspension system from KYB Japan. There weren't any English reviews to pull from as the systems isn't offered or distributed in the US at least. But that doesn't mean you can get your hands on it. So I sourced them from RhdJapan.com whom I've used in the past.

Enough back story on to the setup.

KYB advertises a Front 29mm drop with a 3kg/mm spring and 27mm drop 4.3kg/mm rear spring setup. Barley higher rates than stock. Good so far. The dampers are OEM style with the rears being adjustable.

Like the rear Bilsteins offered, they are longer than stock but only by ~5mm. The damper adjustability from 1-14 more than makes up for the tiny loss in bump travel.

Shock dyno, digressive in nature. I currently have them set to 6. Setting 4 is easily smoother than OEM.

The install was straight forward.

The finished product.

Not pictured are the 20mm front strut spacers to level the chassis. The rear is higher by 1/4" measured at the pinch welds. For what I wanted this is much better over the OEM 1" rake. Additionally I am running camber bolts on the upper knuckle mount to add camber and equal the rear camber gain. It looks to be around 1-1.5 degrees total. The springs should be settle now as it has been over a week and I can now take it in for an alignment.

Cheers!

Looks really good, but it looks like more of a drop than 29/27mm to me.

My springs are supposedly a 51mm drop, or nearly double that:

Question: are you able to adjust those dampers to a point where they are softer than stock?
 
Did you by chance get a pic of the part number for the rears shocks? If so can you confirm it is WSB2159?

You know I think you are right, they look closer 35mm.

Yes you can adjust them softer than stock for sure.

OOOOOF this is NICE! 2 Questions: 1) what size are those wheels, 20in? 2) Did you paint the mirror caps/door handles or did you pickup some aftermarket covers? Been wanting to do this for my white cx5 but am unsure of the correct way to do it. Thanks!
 
The wheels are 20x9 +38et with 255/45r20 tires.
The mirror caps are OEM. The black handle covers however are from aliexpress.us. I imagine Amazon/ebay would have them too.
 
2 months in, and I still love the setup. I am running front camber bolts with F&R camber setting of -1.6-1.7. I haven't noticed any additional tire wear since toe kills tires not camber unless we are talking autocross levels of neg camber. I have taken it on my favorite twisty back roads and it performs great, but an CUV. Could use sways or at least poly bushing all around to reduce body roll but, the lack of seat side bolsters doesn't inspire enough confidence to continue handling mods in my eyes. Maybe its time for an ECU tune...
