GavinL Posted October 15, 2001 Author Share Posted October 15, 2001 Quote: from Doughie on 9:39 am on Oct. 15, 2001[br]Looking at the two anti-roll bar options from TRD : One +27% all round, one +50% at the back. I would not advise personally going for the "+50% rear only" option as increasing rear anti-roll stiffness has the effect, (certainly in race cars), of *increasing* oversteer (or conversely, decreasing understeer). It sounds counter-intuitive, but if the Supra responds in the same way racing cars react by stiffening the rear only then you may get more oversteer, and this is not what you want on a powerful car like the Supra ! The boys on US list were looking into getting +43% front bar made up to compliment the +53% rear. They were suffering oversteer problems as you suggest.

Nick Posted October 15, 2001 Share Posted October 15, 2001 I wouldn't assume that the TRD anti roll bars are of unquestionable quality. I have a TRD strut brace and after just one year the paint has started to flake around the mounts and it's starting to rust. I'm not impressed.

Rich J Posted October 15, 2001 Share Posted October 15, 2001 I understand that the stock anti-roll bars are hollow, if that is the case they may well beef up the tube thickness internally, keep the same overall diameter and retain use of the original bushes. I will try and clarify this with MVP Motorsports when I contact them. Yes they are hollow, and the whiteline ones are SOLID Quote Link to comment Share on other sites More sharing options...

Yes they are hollow, and the whiteline ones are SOLID S'cuse me Rich but there was a point higher up regarding what comes with the Whiteline kit I was expecting you to answer. Gavin, the main reason rubber bushes are fitted to cars is to try to reduce the noise transmitted from the road, engine, etc. but you don't get something for nothing. The ideal connection is solid everything but that will rattle your teeth out, so you compromise. The moment you fit a rubber joint in the suspension you get changes in geometry every time something moves, i.e., over bumps, when braking and just general flexing. Therefore the more solid you make your rubber bits, the better it performs and the more noise is transmitted to the bodywork. I was interested in the stock+27%, the +50% seems ridiculously stiff for road use and matched with a +27% front, it's going off on the first bend; Yeuch.

Rich J Posted October 15, 2001 Share Posted October 15, 2001 S'cuse me Rich but there was a point higher up regarding what comes with the Whiteline kit I was expecting you to answer. Missed it, OK whiteline kit includes 4 springs 4 Koni (rate) adjustable Dampers (moveable platforms for hight adjustment) front anti-rollbar 30mm 50% uprated (adjustable, 2 position) front lower rear arm bushes, and front lower front arm bushes (makes the steering more direct) (urethane) front anti-roll bar bushes (urethane) front drop links (very beefy) (urethane bushes) rear anti roll bar 20mm 30% uprated (adjustable 3 position) rear anti roll bar bushes (urethane) you use the standard rear drop links but I think you can get uprated ones seperately.

Paul Booth Posted October 16, 2001 Share Posted October 16, 2001 Interestingly, I was looking at the Fensport site (TRD) and they're starting to do a full set of Polyurethane bushes for the JZA80. They've got both Koni and KYB shocks, springs, oh the works, and at what seems on the face of it, quite reasonable prices. Guess what's just gone on to *my* shopping list? *pardon*, *what*, you'll have to speak up, the tyre noise has made me deaf Quote Link to comment Share on other sites More sharing options...

Even over scabrous Norfolk roads, there is enough give in the suspension to avoid bump steering and too much tramlining, I think it was set up spot on - any harder would be over the top. Dunno if the roll bars were uprated, I must ask, after the earlier stiffer suspension vs uprated rollbar rant. -Ian Quote Link to comment Share on other sites More sharing options...

GavinL Posted October 18, 2001 Author Share Posted October 18, 2001 TRD anti-sway bar kit - quotes from Supraforums chaps: Quote: The kit reduces body roll slightly and didn't noticeably hurt ride quality. I'd recommend it. It comes with new sliding-type mount bushings, and re-uses the stock end links. Quote: Be sure to lube the bushings properly and be ready for it to squeek some till the bushings get set good. regards..............

THOR Racing Posted October 22, 2001 Share Posted October 22, 2001 Just a little note to say that I've just fitted some KYB AGX adjustable shocks over some Eibach springs. The ride is much lower and the look of the car is great but driving is more tiring. The ride is harder even on the soft setting but the car really sticks to the road now. http://homepage.ntlworld.com/peter.betts/supra/TechTips/kyb1.jpg http://homepage.ntlworld.com/peter.betts/supra/TechTips/kyb2.jpg http://homepage.ntlworld.com/peter.betts/supra/TechTips/kyb3.jpg http://homepage.ntlworld.com/peter.betts/supra/TechTips/kyb4.jpg Take your pick.

THOR Racing Posted October 22, 2001 Share Posted October 22, 2001 Note that KYB AGX's are NOT available in the UK so any dealer advertising adjustable KYB shocks mean the standard gas adjustable. These differ in price and method of adjustment. i.e. the AGX's are adjustable via a small screw in the top of the strut. How much for the KYB's in total? Price.. £115 each ....total =£460....... N.B ..Koni adjustables(Fensport) £118 each ..total =£472 and these need to be removed from the car to be adjusted..... The other KYB adjustables come from places like Fensport known as "self adjusting shocks", (Gas-A-Just) £55 each.....They dont have any adjustment on them,and the ride was crap on Darrell's car...... The KYB AGX shocks have the dial on the top of the shock to alter the damping force.Check www.kyb.com/shocks2.html for more info.... Kayaba UK dont stock KYB AGX shocks ,only available from japan or the US.. Regards Pete Quote Link to comment Share on other sites More sharing options...
