Folks, I've now had the Autorunner coil spring adjusters installed on my 2003 Old Honda City for a month, and they work just great. Thought I'd share my experience with the good people on this community.
Upon reading about the experiences of GTO and others, I decided to go in for the Autorunners. After some hesitation about whether to get a 1" pair for the back wheels only, I decided to go with the advice of Darryl Menezes (the gentleman who sells the Autorunners) and had a set of four shipped over (1.5" pair for the front, and 2" pair for the back end of the OHC).
The installation process sounded simple enough, so I resolved to attempt the job myself instead of taking the car to a mechanic. Now I'm not one of those do-it-yourself blokes, so there was definitely some trepidation going in.
Armed with liquid soap, a water pan, an old floor mat, and my 8-year old daughter as a trusty helper, I headed down to my parking spot. And hit a roadblock right away -- the rubber loops looked simply too tall for the springs and impossible to fit into the gaps in between. Uh oh... had I gotten the wrong size (too big)?
SOS call to Darryl... straightaway he asked me if I'd jacked the car up first... Aha! Once jacked up, the wheel springs were fully extended and now the gaps didn't seem that daunting. After getting the tyres off, I soaped up the first rubber coil and started putting it in. It takes quite a bit of pushing and shoving to get one end in, and then becomes progressively easier to snap the rest of the length into place.
My car's spring has three turns of coil; I inserted the rubber loop into the center gap as I wanted it to come into play under mild to full load. The rubber curves around and wraps a bit of the upper and lower turns. The coils on my car are wide enough around (i.e. coil diameter is bigger than that of the rubber loop in its natural state) so there was no overlap and I didn't have to cut any length of rubber.
Per Darryl, for best results the 'split' on the rubber loop should 'face' outward on the front wheels, and inward on the back wheels. Now I don't know if this actually makes a difference or not in terms of final compression support on the springs, but went with his input anyway and installed them accordingly.
It took me a bit of experimentation to get this alignment right while shoving the thing in. Overall, the installation was a simple enough procedure that even a novice could handle.
After approximately 30 mins of sweat to get all four pieces fully installed, we were ready to roll.
The car looked noticeably taller than before in its normal stance. Had an opportunity to 'stress test' right away -- five hefty adults averaging over 80 kilos each, plus a full complement of luggage in the boot, on a 15-km drive from CV Raman Nagar to Whitefield. As Bangaloreans familiar with this route will know, there are some badly potholed patches along the way as well as several massive "axle breaker" speed bumps.
For someone who'd become resigned to carefully 'angling' over each mountainous hump at a snail's pace, this drive was a revelation -- the new Autorunners allowed me to literally sail over all comers at a goodly speed despite the fully loaded vehicle! What a difference the right equipment can make!
The first few days, I found myself constantly checking to see if the Autorunners had popped off. But no worries, these puppies were safely locked in place, and soaked up every nasty pothole or speed bump I threw at them. In terms of vehicle handling, there is not much of a difference.
Initially the car does 'feel' higher off the ground when you're in the driver's seat, but you get used to it quickly. Since all four ends are raised, the car doesn't slew around lopsidedly, and the handling doesn't change under hard braking either. The ride seems a tad stiffer, but that is not necessarily a bad thing.
Now, a full month later, I am a very happy man and consider every rupee supremely well spent. I can brave any reasonably motorable sideroad instead of cringing at every speed bump like I used to. At INR 4300 for the set of four spacers, this is easily the best investment I've made on my OHC since the day I bought it 9.5 years ago. Bravo, Darryl!
I heartily recommed the Autorunners to all OHC owners, indeed to anyone who drives a relatively low-slung car and is sick & tired of scraping over sundry road bumps.
Cheers,
Nani
