I have a Lexus SC400 and I bought spacers for the SC400 not an LS400. The quality was great and the material used was nice. The only thing is the notch or opening for the spacer to slide into the engine mount was too narrow so I had to file it down like ALOT. I mightve gotten sent SC300 spacers is my guess or they got mixed up im not sure. Also, I didnt really like how the transmission spacers were designed. Yeah it has an opening like the engine mount and its easy to put on but they didnt look like they were going to be secure because of how small they were. I ended up stacking two thick washers on each bolt where the trans mount is which was the same exact height as the trans riser and looked a lot more trust worthy. Overall, it was okay. Hey at least everything is raised now lol
