Default Q-Rack (Buyer Beware)

So this has been long over due, but I am glad I waited to write this, as I have more to say about Tibor and Q Rack.

I ordered a Quick Rack from Tibor, and had it shipped to Yimi Sport in Santa Clarita, CA (A Suby shop).

They installed it, and from the day 1, I had horrible steering shutter issues. I had a few other shops look at it, and they all said, your rack is defective.

I called up Tibor, and after weeks of communication and delays, he finally sent me another rack, to which the original (defective one) would be sent back, and he would pay Yimi Sport for their time to reinstall the rack, as it would obviously not be fair for me to pay for install twice on a defective part.

This is where **** hit the fan. The 2nd rack was shipped and made for a 2006 WRX, and I/Yimi Sport had to buy tie rods (on the spot, same day) to get it installed. Tibor said he would also pay them back for the tie rods, as he made the mistake, and forgot what year I had. Anyhow, the rack was installed, but I still have the same issues. This time it seemed a little better, but was definitely not right.

The mod is great, and I love the quick steering ratio, but as soon as you heat it up, and come to a near stop, such as parking, and try to turn the wheel, it shutters something awful. I even had my pump replaced just to make sure that was not the problem.

Now, here is the main problem, and I feel absolutely horrible for Yimi Sport.

Tibor did not pay them for the re-install or the tie rods as promised, and has completely stopped communication with them. He does not return emails or phone calls, and that includes with me as well. They are out about $500.00, and left with a defective rack. He was supposed to provide shipping info to return the rack.

I just thought people should know what they are getting into before purchasing his rack. Not only is it not street friendly (shutters like crazy), but, he did not keep his promise of paying Yimi, and to me, and that by definition defines horrific customer service!

Kind of weird, that he did not even want his rack back.

You sure it's the rack and not air in the system?

air in the system, a year later? I had it checked by several shops. It's the customer service that irritates me more.

So, I put an STI rack into my 2001 RS. It was generally great, but I would get a shudder at full lock. I was also running an underdrive crank pully and it turned out that with the underdrive pully that the RS PS pump couldn't power the faster rack while being underdriven by the smaller pulley. I swapped out the underdrive pully for a stock sized crank pulley and the problem dissapeared.

It sucks about the customer service issues, but I'd also tend to agree with Jamal, you've put in two racks and have the same problem. I'd look for potential issues like air in the line, or not a strong enough PS pump. The STI's have a faster rack and they get a bigger PS pump. Your new rack is likely faster than an STI rack, I'm guessing your PS pump just can't keep up.

Why did they buy new rod ends? Couldn't they just have scavanged the tie rod ends from the original (bad) rack?

wish there was a stronger pump, but there is not. I even have a cooler installed.

It is made for the stock pump.

They had to by new rods THAT DAY, since the car was taken apart. It was made for 2006, not 2002, so the bad rack would have not worked.

I know its the rack, as I can turn the tires (up in the air) and it shutters, that's how the shops knew it was the rack, and nothing else.

Did the shop change the weak hose clamps from the reservoir to worm drive clamps?

I would agree. It took numerous lock to lock cycles to eliminate the shudder I had. Also, might be time to check line pressure.

And my years of diagnosing issues on the global level say look elsewhere if two racks exhibit the same exact condition.

ya, i actually saw this thread before, trust me we checked EVERYTHING. We replaced the clamps.

Air in the system a year later is a little weird. Either way, when the car is up in the air, and you move the wheels, it shutters.

Also, when looking at the reservoir, it shows no bubbles.

guys, it's not the rack. I had Suby shops check the problem. I was letting everybody know how ****ty Tibor is, and how Yimi Sport did not get paid.

I have delt with the shutter as I only notice it at stoplights, or u turning, or slow movements.

A little odd, that he did not even want his $1200 rack back

I will pay somebody in the LA area a pretty penny if they could discover it's not the rack, and a simple fix such as air in the system.

When I was at the shops, they hooked a thing up to see if there was any pressure/air in the system..

Well, Yimi Sport didn't get paid, but they do have a $1200 rack out of the deal. A rack that in all likelihood isn't actually defective.

I think that Yimi Sport would disagree. Do you think they would have gone to the trouble of doing all this for me, if they could have solved the problem. Nobody wants the rack, and they would never sell it, due to my situation, and Tibor's poor customer service.

It just sits in the back. It's quite sad really.

Can I have it if I pick it up? I'll bring beer.

I can also take a peek at if you want Sunday AM. I've got about 50k flawless miles on mine.

apparently these have a very specific bleeding procedure and shuttering, even in the air, is not unheard of if not done properly. Not saying yimi doesn't know what they are doing or anything. I don't think these racks come with instructions or anything so it would be virtually impossible to know unless someone told them.

seen here step 17 onward is the bleeding instructions.

Yimi spoke to Tibor during the install to confirm. It's no different than installing a stock rack.

Actually, I also think it's not the rack, and that the shop is wrong.

Biggest thing is that the q-rack is just a stock rack that's had new teeth ground onto the shaft and a new pinion installed, AFAIK. The whole proportional valve assembly is stock, all the material is stock, it's just slightly modified. Not sure what could go wrong identically in two racks like that.

Moreover, I know Tibor has sold a ****load of them and I've never heard of this issue before.

That said, he is really hard to get a hold of, which sucks.

i was just noting that it's interesting. it may be quite a poor reflection on the shop if you guys turn out to be right

maybe some metal filings or something didn't get cleaned out properly when making it? the tech just absent mindedly forgot to do something simple like that?

+1 the shop likely wrong.
Two setups, first a 2002 WRX steering pump, then a JDM Sti, rack is holding up, no problem.
I bought it used, Tibor offered full support, I never needed it.
And getting the air out did take a long time...
