so my steering wheel has a wobble at high speeds. i have d2 coilovers and low profile wheels so is this the cause?? ive taken it to two shops and they cannot figure it out. ive gotten use to it by now but id like to know what it is. outer tie rod ends were replaced. i know when you lower a car it never rides or handles the same.......
let me know you guys opinions or if i should even worry??

 

Tires balance? Wheel out of round/bent? Rotors good?

ITR's OK, LCA's ok?

What does the shop tell them and what do they check and what do you tell them?

I've had this many times in the past and it was 99.9975% of the time tires were't balanced or a weight fell off causing an imbalance.

 

I have the same issue but mine is due to the wheel being warped ever so slightly. with proper balance it only shows above 70.

 

itr's are ok. the wheels were recently balanced and the guy told me they balanced with no issues. i told them to check over the front end and after i did the tie rods everything checked out ok. maybe i should just get them rebalanced somewhere else??

off this topic for a sec. would a smaller wheel be more efficient? my 20's seem heavy and kinda big for the car so would some 18"s and stock tires off a g35 help with mpg and handling? i figured since a smaller wheel =less weight.....usually

 

I saw my best improvement ion MPG's when I went to lightweight wheels.

Not a fan of 20's myself, and that's certainly not helping the situation.

Try a place with the roadforce extra fancy tire balance machine.

 

know if g35 6 spoke 18's are lightweight????

now my rotors do need replacing but they dont cause wobble under braking load so im guessing they are straight

 

I have those wheels and if I recall they are 22lbs each so technically they are light weight, but for me is has to be under 20 lbs.

 

Mine were 14.3.
