OLD posts from years ago lists you can buy the supra subframe mounts to mount the rear sway bar and the cost is around $55-65 x 2. Today's price, after tsunami and toyota price hike etc, I didn't find these mounts for less than $93 per side.

Does anyone have a better source for price?
It doesn't seem to be practical to be adding around $200 on top of sway bar cost.

Is Daizen still in business because I heard their bars are made directly for the SC300

 

Daizen is no longer in business. If you want SC300 specific sways go with whiteline sways.

 

I think I paid about $93 per side for new MKIV mounts and I haven't looked back. The prices have been like that for at least 3-4 years. I picked up a used 93-96 22mm TT rear sway bar for $45 and paid a tiny bit more for new bolts, factory U-mounts and corresponding rubber. I feel it's been completely worth it from a handling standpoint but it depends on what you want to do with your car. I was going to suggest Daizen but then I read the above post. Yes, 2nd best would be Whiteline.

Still, I think it's far better to anchor the swaybar to the rear subframe rather than at the trunk if you want to focus on the best handling potential over comfort. Whether $200 for the mounts alone is worth it depends on how you ultimately intend to use your car.

 

On my new project sc300 I bought supra mounts and cusco sway bars for mkiv.
Its an awesome setup! well worth the money.

 

The SC300 isn't a Honda Accord. It comes with good sway bars from the factory. Unless you specifically need thicker bars getting them would be a waste.As I said before a 92 SC300 has the same size front sway bar as a Supra. Furthermore most aftermarket sway bars aren't even thicker than the stockies.

 

so if the aftermarket are the same size, are they made out of a different material with increased modulus of rigidity or to decrease the deformation?
Or would the increase in rigidity come from mounting the sway bar to the subframe not the trunk?

 

I have a complete Daizen sway bar set for sale in the classifieds.

 

you just have to be patience and wait for the deal...
I just bought tt sway bars and mounts for 150 shipped
