After adding all the bolt-ons to my 2008 Evo X and pushing over 340whp with a tune from WORKS Motorsports (www.worksevo.com) it was blatantly obvious that I needed to address the lackadaisical handling of the vehicle. Body roll was ridiculous and the car felt far less predictable compared to it’s OE state . On tight turns at the track I was often in tripod mode with the inner rear wheel floating around in the air as the Evo pushed through the apex. In Turn 5 at Mosport International Raceway we would even get both inside wheels off the ground, Gates311 style (see photo on right).
Now, my Evo X is not a daily driver so the car doesn’t see many side streets, ramps or backroads. I mainly drive it back and forth from the race track (and maybe for a tour on the occasional hot date). So with that being said, sacrificing comfort level was of no concern and I was in the market for a no compromise, top-of-the-line suspension setup (…and my date would just have to deal with it). Sure, upgrading my swaybars or adding an anti-roll kit and chassis re-inforcement will all help with this problem, but I felt that the root of the issue lies in the suspension itself…
I ended up deciding on purchasing some HSD HR coilovers at www.hsdcoilovers.ca. From what I’ve learned, HSD is a Korean company
and their parts are used on OE equipment. Their HR line of coilovers are a mid level coilover for a pretty decent price…now I know I said “top-of-the-line, no compromises”, but the sales guy assured me the HSD’s would be up to the task.
The HSD’s install as any coilover would and it took me about 2 hrs to install in my garage. One thing that made the install simpler is that the HR’s height and spring preload are independently adjustable, making changes to the ride height quick and easy.
Construction and material quality are on par with some of the higher end coilovers I’ve used in the past. Although I’ve had zero issues with it, the only thing absent on these coilovers for the Evo X is a clip which routes a wire around the back of the strut body. All that needed to be done was torque the mounting bolts, tighten the spring retainer, adjust to desired height and dampening…then off to see Devon @ Powell Motorsports Race Shop in Port Perry, ON for a 4-wheel laser alignment. (See Photo below) When Devon saw that I was running HSD suspension he mentioned that they are using them in some of the race Cobalt SS and have had good results so far. Not a bad endorsement coming from one of the top driver’s in our region! This made me feel more confident in my purchase and now I couldn’t wait to test them out on the track.
Overall the HSD’s perform very well on the track and I’m happy with the results. The car stays flat in the corners and although I haven’t had the chance to dial in the suspension quite yet, the handling is way more precise and predicatable. I definitely haven’t experienced any tripoding and we are flying through Mosport International Raceway’s Turn 5 with all four wheels firmly planted.
There’s no comparison to the OE struts and TEIN springs that I was previously running- the HSD’s do their job very well. They are a bit stiff for rough roads but the ride quality on the street isn’t bad at all. Looking at it from a Cost vs Performance stand point, this is one of the best Mod’s I’ve made on my Evo X.
Best thing about it…utilizing the camber plates we added a couple degrees of negative camber to the front wheels and fit some massive Enkei RPF1 18×10.5′s wrapped in 275/35 rubber….And the best thing about that is- chicks dig it
