- CAD designed, FEA tested, CNC machined ends and TIG welded
- V5 arms include offset bush spacers for even more clearance

I bought Gktech castor arms for my R32 Gtst hillclimb/super sprint car after watching a video on the product and was keen on the idea of additional caster angle.
I am wrapped after the fitting and having an additional 2degrees of castor over my old ajustable arms. The additional clearance was not required as my sway bar is in the way, the sway bar was not a factory item and was purchased to clear a larger sump.
I have sine replaced all the rear arms and had an alignment and am looking forward to a run this weekend
Stoked to be able to purchase Gktech Products to keep my project going. Great Service and thanks for supporting drifting throughout the scene
Got these for my r32 to adjust caster and the install video made it super easy to put in. Wish the supplied nut and bolt weren’t different sizes but that’s just a pet peeve. Car drives noticeably better now.
As always with GKTech gears great quality item and nice package :) Fit perfectly on my RS13
Absolute brilliant product, was a breeze to install with installation video and even a laugh with Officer Dan voice over. Quality second to none and the best part, Australian made 💪
