I will soon be dropping my open diff to replace with a welded one.
Car will be used 75% of the time for drifting and casually a cruise or meet.
With my car been from 03 i think its time to replace those bushings ( besides some clunk noises i heard )
A lot of great companies and great reviews at different price ranges.

*-Whiteline- comes in at $235 for their subframe and diff bushing kits.
*-PBM comes in at $255 for their subframe and diff bushing kits.
*-Sikky - comes in at $328 for their subframe and diff bushing kits.
*-SPL PRO - comes in at $343 for their subframe and diff bushing kits.

all these kits are + shipping ( at the time of this post )

i'd love to see your input on:
Quality of the product.
Shipping time.
installation difficulty.
ride improvement.
any extra info would be great.

For your use, I would go solid bushings.

Z1 solid bushing set is $118

I have the Whiteline poly bushings since my car is a daily and I love them.

i looked at them unfortunately they don't offer a sub frame bushing kit, only a diff bushing kit. ( made by them )

Go solid. I've had whiteline bushings (twice) and solid bushings and can say without a doubt, go solid. The whiteline bushings are simply not made for anything over street performance.



This was the first whiteline differential bushing and failed in the first track day.

I didn't notice any difference with the WL bushings on the diff.
Good for daily but go solid for track\drift usage.

'Best' is subjective.

i figures solid might be the way to go. anyone has experience with PBM?

pretty sure all the solid will yield no deflection
think it comes down to price mostly

i have the spl

Motorsports application solid , I run SPL diff and Sikky subframe

Daily that gets badly abused (weekend drift, autocros, roadcourse ) solid diff, whiteline subframe. Ran this for a long while.

Just a daily, whiteline diff only. No need to replace the flexy subframe bushings.

CFS_Z

is there a reason why spl and sikky vs both spl or both sikky?

Because SPL was the only diff bushings available when I bought mine , and sikky was the only raised subframe bushings on the market when I bought mine. Now both companies offer both sets of bushings.
