Renowned Japanese Honda tuner Spoon Motorsports has these things called the Rigid Collar, I don't know if you guys have heard of them. It's basically an aluminum bolt spacer that ensures the chassis is perfectly aligned with the sub frame, as apparently the alignement tends to shift with a car's age.

Here's a link to the youtube video explaining what they do.

They are not just for Hondas, but I know absolutely no Japanese, so I can't tell if they make them for the G37 (CV36). Can somebody with some knowledge of the language check out the website and see?

These are quite expensive though, around 215 bucks for a set. Unsurprising for JDM parts though.

 

I've heard of collars before, been following a few blogs and guys with R34 GTRs installing them to keep the subframe from moving around.

Looks like they have them for the V36 Skyline Sedan/Coupe - our cars.
