The current 15" in my opinion is a big risk considering Latio's lightweight body and poor braking power. I'm driving Latio sedan premium , all stock and no upgrades(worry insurance will void if i change any stock parts). If you could actually upgrade both wheels and brake set. I reckon it will improve both the ride, grip and stopping ability of Latio.
I had twice experienced poor braking and grip. Brake has poor response and the feel is not to my liking. Others may find it OK but not me. The thin width of the stock tires is also a disadvantage and a big risk. Its has very poor grip even in dry conditions. To tell the truth, the ABS is consider useless in my car. I was involved in an accident and rear ended a van. Did a hard braking and to my horror, the tires did not grip and yes i kissed the van's rear. I drove a Subaru before this and the braking feel was way different and yes Subaru's ABS does really is functional.
What i realized seconds before the hit, the brakes took sometime to respond and the grip of tires were absent. I literally went flying into the rear of the van. I was about a car distance away and was slowing down. Unfortunately the van in front stopped suddenly. This is just my observation but in my Subaru i had a similar incident before but in wet condition at NSH. I was running on 16' tires with ventilated disc rotor. The ABS kicked in and i could actually feel the Subaru judder. Not in the case in Latio though. I guess we have to factor in the weight of LAtio. Subaru was much heavier and contributes to the tires gripping better on the road. Latio somehow does not have that advantage.
I guess i could drive more carefully but when i realized Latio's lightweight body and puny tires and poor braking system, I just have to warn others of the risk and eventually this accident could actually be avoided. My observations maybe wrong but hey, i was behind the wheel and experience of driving different cars from Japanese to continental cars, i was sure that Latio has poor braking and grip. Plus it's lightweight body. To tell the truth, i had four people on board Latio and the tires can still skid under normal braking. That happened along BKE.
So i suggest if you wish to use Latio for a long time, upgrade to 16' wheel set with wider tires and better braking system. Yet again i maybe wrong in this but in my experience, it says Latio stock brake and wheel set is really a risk.
What you guys think of this? I'm open to suggestions and advise.
