DAMN: Lowered on Eibachs + AWD = Vibration
DAMN: Lowered on Eibachs + AWD = Vibration
Well chalk up another one....
Although the GS350 now looks like all the promotional ads that I was fooled with at the dealership. I have that annoying vibration when I engage the car in Reverse or Drive. it isnt horrible but it does jingle the coins in the center console coin holder.
I have not taken the car out for a drive yet, but I plan to do so tomorrow. I am still running on stock 17's I will try driving around for a few days and see what becomes of it.
I dont want to put the stock springs back in as I'd rather keep the better looking profile with the damn vibration.
I have my new TOM's wheels ready in the garage to be mounted on car in 2 weeks once the springs settle and I make note of all the bugs associated with this install.
After looking at the front strut assembly pretty close, I think it is VERY easy to make a coilover system for this car. the front strut actually unscrews from the "Question mark" looking fork that attaches the upper A arms and lower control arms and steering knuckle. There is plenty of room for a threaded body and adjustability.
I will try to contact MEGAN Racing and see if they are interested in supplying a market everyone else has failed to recognize.

I see what you're saying about the AWD front struts and I was thinking the exact same thing. Can that piece be bolted on/off? For me, I wouldn't dis-assemble the "question mark piece" and assemble onto an aftermarket coilover spec'd for the 2WD. Although, I think it may work. I think the aftermarket manufacturers would like and AWD to test the idea.
As for the other posts. I don't see any problems with lowering the car with 2WD spec'd springs. If anything, the front CV boots might wear faster (depending on how low the car is). The overall design of the AWD system shouldn't be any different from an Audi, Subaru or Mitsubishi and lots of those owners lower their cars. I think the aftermarket manufacturers do not want to spec their components for the AWD yet because they have limited or no test data. Basically, it's most likely a liability issue. Being that there are more customers with an AWD GS (since late 05) and a larger market of owners wanting to modify their suspension, I think that you might start seeing AWD spec'd aftermarket lowering components within the next year.
Im going out for a test drive.... I'll report back this afternoon. The vibration was 100% NOT there before. I made note of these things. its annoying and it does jingle the change in my coin holder. I am not one of these guys that blindly does things.... I been reading all the lowering posts for months, I double checked all the items that could have been problematic, and so far so good.
Let's see what happens.
Im being optimistic.

I had the same problem.. i didn have some vibration before the springs.. the springs really amplified it and dealer removed them at no cost and even put newer factory springs in.. vibration is 'mostly' gone but still occurs on occasion.. sux to be back to 3in gap

Are you serious, how was the dealer able to do that at no cost?

because the problem was still there (although not as severe) after removing them and they upgraded my springs to a newer 'stock' version (apparently there was some factory change w/o a TSB).. so irregardless of which springs were removed, the work was still going to get done anyway.. plus they were the ones that installed the Tanabes for me.. they are a very mod friendly dealership.. most any time you go in there they have an IS or something sitting in the showroom with an intake, exhaust, custom rims, springs, etc.. that you can buy as is.. on a side note, i stopped in yesterday and drove the IS-F .. love it.. will write more later, but i hope they do the same with the GS-F.. love how it downshifts in sport mode.. amazingly fast shifts.. an excellent 'first try' for a lexus performance car..

I understand, the dealer installed the Tanabe's and warranted the work. That's weird, the dealer installed Tanabe springs spec'd for a 2WD on your AWD. I totally understand that they're mod friendly but I'm surprised they installed springs that weren't spec'd for the AWD and warranted the work!

By the way, do your questions refer to a stock of modified suspension?

It's hard to say what the actual reason is, too many factors. The degree of vibration is subjective amongst owners, some may not notice it while other think it's major. The cause and reason for the vibe will need to be investigated more thoroughly.
