greeneyes Posted May 19, 2004 Share Posted May 19, 2004 I was just thinking that I might think seriously about putting a heavier anti-roll bar on the rear. (not that I want a modded car mind you...) What do you guys have and what do you think of them. Have you noticed any change in the understeer, or does the tail hang out more in the rain?? Has anyone just changed the roll bars and not changed the springs? Ta keith Quote Link to comment Share on other sites More sharing options...
?UESTLOVE Posted May 24, 2004 Share Posted May 24, 2004 Id also like to know whats availble! Note Greeneyes, if you put a thick one on the rear only, watch the back come out hehehe. It will make the back stiff, so if you around a corner fast, the back will start to slide...FUN! Quote Link to comment Share on other sites More sharing options...

frylai Posted May 24, 2004 Share Posted May 24, 2004 Squid Installed a TRD One on his rear from me back in the baggining of the year...think you guys should PM him! Matt =) Quote Link to comment Share on other sites More sharing options...
Squid Posted May 24, 2004 Share Posted May 24, 2004 Already spoken to Keith about this, but for those interested: Only did the Rear, but HIGHLY recommended.Obviously as a sway bar, it doesn't change anything in a straight line, so comfort/ride isn't affected. Most noticeable change was the 'wobble' the rear had when shifting the weight from one side to the other. It all but eliminated it, its a shame I didn't get to go round taupo with and without it in, would have been a good comparison. But $ for $, my personal opinion is that it was definitely the best upgrade to do first. Body roll was also reduced, but not by as much as I expected. TRD rear is only 99% stiffer, Cusco do one that is 125% stiffer (and a little cheaper too) so that might be a more noticeable difference in that respect. Interesting difference is the front bars, TRD is 49% stiffer, but Cusco is 140% stiffer! , making for quite a radical difference in final setup between the two. Was going to do front strut brace next, then front sway bar, but got a deal on some hks suspension that I'd be an idiot to pass up. Shame, was looking forward to seeing what improvements the different upgrade steps would do. But the handling I've got now, is just amazing. Really looking forward to trackday! Also, suspension setup dictates that increasing the rear sway bar stiffness will increase the chance of oversteer, but the Tezza I have found has quite a lot of natural understeer 'built-in' so adding the TRD bar gave additional turn-in, and to be honest, the only time the back ever steps out on me, is when I'm ... shall we say 'encouraging' it. ;) Quote Link to comment Share on other sites More sharing options...
greeneyes Posted May 24, 2004 Author Share Posted May 24, 2004 That Cusco bar looks too stiff for the front. That creates understeer. The Cusco rear looks good. Hotchkis has an adjustable one for the rear at 144% & 227%! What interests me is the difference between an Altezza, an IS200 & an IS300 to start with. The extra weight in the six cyls and the different springs/ride would suggest different roll bars fitted at the factory. When the Americans talk 125% stiffer I assume that is on an IS300, but Japanese 125% stiffer is on an Altezza. Do you have any data Matt?

frylai Posted May 24, 2004 Share Posted May 24, 2004 Yeah we do have different springs for the 300's I heard even different shocks... I would think it will be the best for you guys to stay with the JDM Tuned Products...Like TRD and Cusco...I think TRD would be the best for overall!

zee007 Posted May 24, 2004 Share Posted May 24, 2004 Keith, Have a peek over on the UK site.... there are a few guys who have just fitted the TRD anti-rolls, I have along with a few others the TTE anti-rolls, and there are a couple of members with the Cusco and hotchkis..... We all have both front and rear - and it was one of the best modifications I have done (and I've done a few....) VERY highly reccomended....... ;) Quote Link to comment Share on other sites More sharing options...
frylai Posted May 24, 2004 Share Posted May 24, 2004 Alright...I think the TTE one is too overpriced, Hotchkis/Cusco is adjustables and the others are not from memory...but the best priced ones are TRD and also it is factory quality, I heard some cons about the fitting for the Hotchkis ones like funny noises. Only the TRD ones are sold seperately...and for a reason!!! Matt =) Quote Link to comment Share on other sites More sharing options...

Only the TRD ones are sold seperately...and for a reason!!! Matt =) Nice summary there Matt..... :) The TTE Anti-Roll bars are actually re-badged Eibach bars and DO have adjustable rears..... I agree that they are slightly more pricey than other brands - but I also feel the quality is excellent (not sure if you have ever seen them as they are European)... Everyone I know (and there are over 30 people on LOCUK) who have ordered sway bars have ordered pairs - as it's not reccomended to have one bar stiffer than the other. I agree, the TRD bars are good quality also. Its nice to share experiences....... Zee. :) Quote Link to comment Share on other sites More sharing options...
greeneyes Posted May 25, 2004 Author Share Posted May 25, 2004 (edited) Thanks Zee. I've kept an eye on your forums there, and I see the group buys were going on. I assume the thickness of the roll bar is proportional to the stiffness. So far- ARC front 216% ARC rear 146% Cusco front 30mm 140% Cusco rear 16mm 125% Eibach front 28mm Eibach adjustable rear 17mm Hotchkis adjustable front 32mm +56% +61% Hotchkis adjustable rear 19mm +144% +227% L-tuned front 49% L-tuned rear 99% Stillen- no data, but usual price of $US336/pair is reduced to $US180 currently. Tanabe Sustec front 30.4mm Tanabe Sustec rear 18mm TRD Sportivo (blue) front 28.6mm TRD Sportivo (blue) rear 16mm TRD (yellow) front 30mm +49% TRD (yellow) rear 19.1mm +99% TTE don't quote % stiffer, they list effective lever arm TTE front 28mm thick, 225mm arm TTE adjustable rear 17mm thick, 90mm, 105mm, 120mm arm lengths TTE are the same as Eibach, and L-tuned look the same as TRD. any more data?? Any comments?? I'll keep looking for NETZ sports & Area 51. keith Edited May 28, 2004 by greeneyes Quote Link to comment Share on other sites More sharing options...
zee007 Posted May 25, 2004 Share Posted May 25, 2004 TTE don't quote % stiffer If you have the Eibach % - it will be the same for the TTE's.... And you have done some excellent research there buddy! ;) Quote Link to comment Share on other sites More sharing options...
Hoon Posted May 25, 2004 Share Posted May 25, 2004 TRD (yellow) front 30mm +39% TRD front (yellow) stabilizer is 49% stiffer than standard according to www.trdparts.jp Quote Link to comment Share on other sites More sharing options...

Sportivos are the blue TRDs, 28.6 & 16mm TRD yellows are bigger again 30mm and 19.1mm I'll keep editing the main post there as I can update info. I corrected a couple of things just now. keith Quote Link to comment Share on other sites More sharing options...
greeneyes Posted June 4, 2004 Author Share Posted June 4, 2004 In the end, I've bought a rear Cusco bar from our own happy supplier Matt Frylai. The going NZ rate is $320, depending on the exchange rate. I'm hoping their stiffness data is correct, even tho' they're thinner than the TRD yellow. The first thing will be to set up a test bench and measure how much stiffer than standard they are. Quote Link to comment Share on other sites More sharing options...
Squid Posted June 4, 2004 Share Posted June 4, 2004 If you do get a 'test bench' setup, gimme a yell. I'm happy to whip my TRD Yellow bar out for a comparison, only a 5 minute job. Quote Link to comment Share on other sites More sharing options...
