the articles I remember reading said its rear end rotated well, not in a bad way.. but it has been a couple years so maybe I'm only remember the good parts? and I'm pretty sure I read only 1 article about it.

 

this would make sense, also easily fixed with coilovers...

 

So many reviews of the car mention the bump steer issue. You aren't paying attention.

It's very obvious you didn't actually watch or pay attention to the video.

 

Exactly my thought too. Going to wait for the Ohlins to come out and hope that they keep the electronic dampening function. If they dont, HKS sells some that do for pretty cheap. But then again, cheap rarely means good.

Once my springs come in and I go to install, it is recommended to cut about an inch off the bump stop. We will see how that works out for the time being.

Oh and I tested the traction control on my way home yesterday. Fastest I got up to was 45 mph (thanks Socal traffic) but the traction control still turned on and off as it should.

 

Over on the Supra forum, someone posted the video Razorlab did. Turns out, the guy swapped out the wheels/tires and didnt program them to the car. So it was thinking it still had on the original sized tires and freaking out the traction control system....

 

Program new wheels to the car? jesus.

I thought my VW's were needy.

Def looking forward to you modifying the car and getting 1st (2nd?) hand experience here.

 

Yep, if you change the tire size, you have to tell the computer. It has some sizes preset but the ones that arent, you need a special little programmer to program it or you can do a short drive cycle for it to self learn. Not hard to do but still a pain. Good news is that you can store 2 sets of wheels in the computer. So if you switch between track and street sets, its just the click of a button.

I am curious to see what the mods do too. Next race is May 22nd and I really hope my suspension stuff gets here by then. Then hopefully wheels and tires show up for the race after that.

 

I will add all of that into my list of "reasons I don't like new cars with all their gadgets "

 

So if you do the self-learn cycle, you can switch between sets from the car's built-in interface? No extra hardware required?

 

So true. I thought my cobalt was fancy cause it has cruise control. Then I get in the supra and get lost with all the buttons...

yes to a point. Certain size tires need a separate programmer. I will have to scroll through the menu to really see what sizes there are. Haven't looked too deep into it yet. I am thinking at a worse case, I can find a pre programmed size that matches the overall diameter of what I'm going to run and just set it to that.

 

I did say I only read 1 article about it, I watched a few review vids. of the stuff I've seen and read, Misha and Robert were the only ones that complained of the bumpsteer issue. I did not read and watch every single review. but out of curiosity, can you provide a link to an article or video of someone other than these 2 (or anyone in their circle) complaining of the bumpsteer?

I didn't watched the entirety of this video, but I did all the other vids Misha and Robert did on the subject. I'm also not arguing what the right way to fix it is, just replied to lumpy sticks's post about it that it makes sense to me.

just a word of caution, if you're going for the standard Ohlins DFV model, some of their applications have travel limitations. Reason is they have limited shock cartridge lengths, I think like 5 different lengths (forget the exact number, but its single digits) so they'll make up for it with mounts. but in some applications it doesn't allow for enough travel. S2000's and NC Miata's (I have Ohlins on mine) are 2 examples of this, both on the rear. Limited travel sometimes makes for exciting handling under the right conditions. Its definitely not an issue on all applications, just something to verify before buying.

I'd recommend KW since they design shock lengths for each application and don't deal with the whole separate height adjustment bandaid, but they just keep going up and up in price. You can usually get a set of MCS coilovers for what a set of KW V3's cost, definitely for what anything higher up the totem pole costs. and MCS dampers are just magic...

in my experience (not Zupra specific) its not usually speed but if you're within some amount of time of when it last engaged TC. if you do something on a car with TC on that makes it engage TC, a lot of them won't let you turn it off for a few seconds after. Given that he was driving on the nurburgring, it could have been in "don't override TC" state during the whole lap? But I didn't watch the whole vid to see how he tried to turn it off so I could be wrong.

this is a thing with any semi modern car... if you change the tire circumference ratio from to rear too much it'll do funky things with traction control/stability control/whatever nanny/sometimes even ABS.

 

I believe KW does make a set that retains the electronic control. I am also a dealer for them so I can at least get a discount! Motron.... great for sure, very expensive.

 

Kw is in my back yard. I probably know half the develop team
if you need any technical information, let me know. I can probably snag it for you

 

Well I think I was wrong about KW being the ones that kept the electronic portion. Maybe you could see if they have something in the works?

RSR is the one who makes the electronic style coilovers. Not badly priced either. About $2700.

Really dont want to switch to a normal coilover. If I have the technology there, might as well use it. I really like that if I put the car in normal mode, it rides very nice. Put it in sport and it feels solid.
