This item actually isn't even for sale anymore from Laile on their Ebay page, and you won't find any American vendors with this product. The only place to find it on the Internet is on Laile's Rakuten page and you better know Japanese.
So if your a JDM parts nut like me, or just want that last little finishing touch to your GC/BC, this is a great piece. I paid $150 for it so I think $100 is a fair asking price for something that isn't even available anymore. The brace is new in box and comes with the sticker, instructions and hardware kit. It's even signed by Ryouichi Takamori of Laile Co.
Here are some badly translated reviews:
Basically it takes 30 minutes to install because it does not require the differential to be removed, or the old bushings. Other bushing kits require you to press out the old bushings and press the new ones in. This just goes right over the top of what you already have. But since it does lock down the rear differential your going to hear gear noises and whining from the rear end. Personally, I prefer to hear my car working so I think that's a good thing. But if this is for a luxury cruiser, you might want to skip it.This product is a joy. Once stability has increased very straight exchange. I think it is a great product that can be converted easily in effect may have been too deferential Hazusanaku a little tough.
