GRK RWD Setting Memo

07/20/2015 at 12:01 pm

Finally got around to installing a multi link rear suspension using left over WUN parts I used to run in the front. I liked both bump in and out so I’ll have to do further testing. I’m also liking the high lever ratio in the rear, but also tried mounting the shocks to the knuckles but that didn’t feel good. Small modification to the front Ackermann made the biggest change though. Car now picks up speed pretty quick so I can keep up with CS running the same tires.


大気開放 Damper

So I’m not a huge fan of damper maintenance, and the way I currently build my dampers shortens the maintenance cycle a little. I wanted to keep a similar damper feel to what I have now, where there’s minimal pressure build up on the top of the diaphragm. This way the dampers are linear and won’t rebound due to diaphragm pressure.

I’m not sure what the english term would be but drilling a hole on the shock cap is fairly common shock build method in Japan. The new GRK Globals come stock with the hole drilled out as well. Depending on the hole’s diameter you can change the feel as well but I went ahead and started off with a 2mm drill bit.

After talking to a local drifter, Jimmy, I decided to rebuild my ball differential in the GRK RWD.


Small Update?

I’ve been neglecting my blog for a bit. Here’s a small update of what I’ve been up to.

RWD, First Steps

I’ve been enjoying CS a lot recently but I might switch back to RWD for a month. There’s been more RWD drivers popping up recently at Super G, and after switching the front end on the GRK RWD I haven’t gotten a chance to tinker around with it much.Tatsuken on GRK RWD

Since the GRK RWD is slowly starting to drive good on carpet, for memo purposes.

Both Overdose and Wrap Up sells a 7075 aluminum chassis now, and it’s interesting how stiff chassis are trending now. My guess as to why they’re coming out with super stiff chassis is because of the abundance of springs and suspension components now.

The GRK RWD is sorta done, and it sorta runs now! I have no idea how to drive rwd, and the car has a long ways to go in term of set up as well. I enjoy driving the DIB a lot more so it’ll take a while until I’m happy with this guy.
