I have been running this MT-01 from HWL for more than a month now so I guess it will be a good time to give some insight on this. I bought this at a bargain price of less than 900 as the shop is shifting to a new store I bargain very hard with the shop owner and I'm happy with the price I got. Then off to my factory for installation (I'm not doing cars just that I have a workshop and tools to do the job) my stock suspension was pretty tall given that I have swap in 15 inch the gap between tires and fender was very wide and there was more roll on the car.
In the beginning I opt for a 8K , 6K spring from the shop owner and brought it home. I was given 1 week of trial if I wanted to change the spring.
I took me 2 hours to setup and install. You need to use back the stock top mount for both front and rear absorber. Learning from my previous bitter experience on lowering (too much). I told myself to maintain the drive shaft close to water level so that the CV joints and the boots won't suffer from excessive angle due to lowering so I went on to set the suspension to a lowering of rear 2.5 fingers and front 3 fingers gap. This retain the daily drivablility of the car and take into account the gazillion of speed bumps we have. With this setup I can clear every speed bump just like a normal car no need to go side ways or scare hit the chassis.
After 2 days of driving with 8K,6K setting it was a very damn poor choice. The ride was totally HARSH to the bone, then it struck me that the gaga is not a very heavy car so 8,6K setting will perform very nice on track but not on street. For the 2 days, I went up and down every road I can imagine, housing area, trunk road, highway..etc...ride was just HARSH any sane passenger will curse me until the sun goes down. Driving feel and stability was good on flat roads and flat corners but not when I hit those yellow line, road gap, repaved gap. The car just lost it stability. I put the car back on jacks took out and spring and went to swap for a 6,4k setting which is the preset spring that came with the MT-01. (double job for me, because trying to be a white rat) Another 2 hours spent on putting this back. The 1st thing I notice when I change the spring for the back from 6 to 4 the 4K spring is shorter so I needed to readjust my height collar for the rear.
Out for a test drive, this time the car is more humane and forgiving when it comes to bumps and gaps. The rear won't hop over those uneven surface anymore and will go through them but the rebound was a bit too quick but I get used to that after more driving test. The tail now follow through nicely on turns. Then next day was ZTH TTA..A good place to test out the suspension. The 1st thing I notice is how the car will turn in when it comes to a corner, previously when I turn the steering the car will roll a bit then turn but now it's gone. The moment I give input to the steering the car will turn in without roll the back was a lil on the soft side and I can feel the roll at the back but still managable. With this installed I've told myself that the tires will be wearing off faster due to the harder setting but over 1 month now my tires are still good. The car now has a very nippy handling and quick steering response from sudden steering input. A few times I tried avoiding cars that turnnig out of the junction without stopping on my stock suspension I have to give more input to the steering to get the angle of turn I needed to avoid but now I don't have to input too much which is good in case of wet road condition so that the car won't risk loosing control.
A difference between the rear installation of HWL and GAB is that HWL has it's shocks and spring made into a single unit. Instead of spring and shocks. I don't know the real reason for this but I'm still searching around for answer.
Comfort wise, it differs from person to person, for me I'm used to it already. I can feel every bump from the road through my steering. The reason I opt for HWL is because it can be service, been in the market for a long time, bargain price, I got a local shop here who has Top Perfect guy coming down to do service and shorter time while GAB I have to give it to the shop and they send it to KL to repair.
Before deciding on HWL, I have made some calls and look around for sport spring. I've look at GAB SS but this were made according to Savvy spec so they are prone to sagging if put on saga (my cousin's saga the best example) I also went to Rosli Smart what they do is drain out the stock absorber oil and inject a different oil to make it harder old school way, I also make inquiries on ProRide but the seller never ever reply my e-mail.
The HWL MT-01 is not the PERFECT adjustable I would say, there are still some areas that I hope it can be better like the rebound rate but overall it's worth my penny. I'm still doing on going evaluation on this suspension.
Just a note though, Adjustable is not for everyone so you need to look around before you decide what you want. To some sport spring is enough but to some it's not enough.
Just my 2 kupang.
