WHITELINE SWAY BARS
The Whiteline website is very unfriendly. I need parts numbers to order. I'm redoing a 92 SC400; can anyone heko me with finding someplace to order them?
Thanks.

Could someone please help me? My SC300 is in shop getting fixed from wreck and I upgraded all suspension to Supra parts. I'm having trouble finding what is needed for mounting the rear bar up. Could someone please show me a picture or give me a part number for the subframe mounts or cushions needed.

Here you go.
The old SC is on the right, and the new Supra is on the left with the mounts.
However, I must say, for all that cash ($63-80 each) you may want to just get the Daizen bars from TMEngineering.net that don't need the new mounts. The bars are stiffer and fit the OEM mounts.

Thank you. I already have the TRD sway bars. Do you know what the exact name for that part is or do you have a part number by any chance? I'm kind of behind schedule right now. Thanks for the help.

808, you are correct that Whiteline does not have a writeup [yet] on the Soarer. However, I am an active dealer of theirs and let's just say "they're working on it".
What Whiteline does have, however, are polyurethane bushes for the Soarer (re: the bad front outer control arm thread), and of course, the Supra swaybars.

The Supra JZA80 sheet is here:

An article on what Whiteline found with the Surpa:
http://www.whiteline.com.au/articles...raJZA80_1a.htm
And if you go to their "Products" section from www.whiteline.com.au, you'll find links to pdf files for their entire line of swaybars, springs, shocks, alignment aids, etc.

Whiteline swaybar pics 3
Picture from swaybar installation on Toylexmod's 92 SC400.
This shows removal of the oe SC400 rear subframe cushions. Notice also the removed bracket on the floorpan from the stock swaybar. (You'll need to plug these holes.)

I don't know folks, these Whiteline units are definitely not something you want to put on your car. Toylexmods is bragging about the weight of his bars, 500% more than the stock bars...this is ridiculous!
Anyone who knows anything about vehicle performance knows that unsprung weight is one of the number one items that should be addressed. Adding this much extra weight to your suspension components is probably one of the worst things that you can do. Sometimes it's unavoidable, such as when going to larger wheels and tires, but to purposely put heavier sway bars...that's not a good idea at all.
Secondly, the Whiteline bars are 30mm and 20mm if I recall correctly. This only results in an increase of approximately 28% stiffness over the stock bar which is also 30.1mm/1.187" (hollow .180" wall). On the rear, there is no way to actually calculate the difference, due to the different mounting style.
28% of increase is pretty mild, the street TRD bars are approximately 35%, but are hollow...a much better choice. The TRD race versions (not currently available in the US) increase by approximately 162%. Too much for a street driven car. Same issue with the GS bars by TRD.
The Daizen bars we offer have several advantages over this. First and foremost, they were designed FOR an SC, not a Supra. They are also designed to balance the chassis of an SC and have been fitted and tested on an SC. Secondly, they are hollow. 35mm dia, and hollow, with a little over 100% increase in stiffness. The bar is somewhere around 8 lbs if I recall correctly. The rear is also hollow, unlike the Whitelines...more unsprung weight issues from these Whitelines!
The Daizen parts were designed for use on an aggressively driven street car, so they are very effective yet still very civilized. I've read more than one post about fitment issues with hoses, etc. with the Whitelines on other websites, this should be something to be wary about. Not sure which sites, but I'm sure a websearch would turn them up.
I have heard some issues as well with the Whiteline control arm bushings, I think some people on Peter Scott's Soarer site have the specific information. They basically refer to the bushings converting the ride of their Soarer into the ride of a truck. This shows that their products were designed for a Supra on a racetrack, not a street driven Lexus.
Australians also have a very different approach with their performance parts, they are very aggressive and are a lot less concerned with everyday driveability. Most are weekend race cars. Not that this is a bad thing, but it's just not what the American market really desires or wants, especially so with a Lexus. This is why the Daizen bushings were tooled with softer compound urethane, leaving the ride quality virtually unchanged.
Another issue is that the Whiteline bars require so many replacement parts for retrofit. Especially so since they are OEM parts, this is expensive and somewhat nonproductive.
Lexus isn't stupid, if they designed a major structural part this way (rear sway bar mount), I'm sure that mount is ok. Remember, this was their flagship car and no expense was spared for production or design.
Upgrading to stock Supra bars can be a somewhat economical alternative if you can source all of the proper parts at a good price, but you definitely will not get a significant increase in roll control. It will be noticeable however, so some people might be good to go with those. Increases would be in the neighborhood of 20% with this setup.
The Daizen bars are a complete kit, designed specifically for the SC chassis, and provide over 100% increase in stiffness front and rear, and use all of the stock mounting hardware. No significant unsprung weight issues either. Adjustable rear bar too.
The TRD street bars are also a decent choice, but the cost along with the extra parts required could make that upgrade somewhat cost prohibitive. The increase in roll stiffness is not a whole lot either. Pricing would decide if this is a good choice for you.
