Just so you know, you will be sacrificing some comfort if you decide to go with an aftermarket suspension. If you don't plan on spending the money to get a really nice coilover, you may be better off trying to find a good shock/sleeve set up instead; it'll more than likely ride and handle better than a cheap coilover.
If you're looking for some entry level coilovers, perhaps JIC, Tien Basics, or Buddy Clubs would be a start. There are cheaper brands like Megan Racing, but it may ride stiffer than you want, even if they are 32-way adjustable.
Ya I just want a small drop, and I dont want to sacrifice my ride comfort. Still want that Lexus smooth ride ya know?
Usually best bet for not sacrificing comfort would be to get a shock/spring combo. There are a lot of aftermarket springs for the 350, but in searching, I couldn't find a lot of options for shocks.
Looks like Tokico is one of the only companies I've seen that make shocks for the 350:
In choosing, you're also going to want to check the spring rates and match them with the shock.
If you look into the F-sport spring/shock, you'll get a small drop and still retain some comfort. It's all going to be based on how you want your car to ride/perform and if you're willing to give up any comfort for performance or looks.
