I bought a set of Titan custom made absorbers more than a year ago.
Funny thing is, I bought the absorbers long before I got the Airtrek, and they're still new, have not install & use them, still kept nicely in my store!!
Didn't use the Titans coz when I bought the Airtrek last year, the previous owner had just replaced all 4 stock absorbers few months earlier, & they're working fine. With the stock absorbers, though the ride is bit stiff, but it does control the body roll pretty well.
I might consider selling my new & un-installed Titan if anyone is interested. The set I bought uses stock coil springs for comfort & they cost less, paid RM2400 if not mistaken. Still comes with warranty & 2 free setups. Any takers? lelong lelong.....selling cheap!!!
