About 45 days ago I installed Tanabe coil springs NF210 for the AWD model (as per Tanabe web site). Drop is : front 1.0 rear 1.4. Not a big drop. I started to have vibration issues at low speed (0-25 mph) and above 50 mph car was vibrating just like when you have a bented dammage wheel or snow inside a wheel or when you loss some balancing weight. At first, I tought one of the wheels lost some weight. After wheel balancing and suspenssion and direction verified by a tech (no issues found) car was still vibrating. So I search on the internet for similar issue. Found out that I was not the only one having vibration issues after dropping an IS250 AWD model. I search and didn't found any solutions. So I visit one of my mecanic buddy. Found out that axle shafts angles change (due of the drop) and shaft was too tight. Velocity joint was to tight and was creating a vibration. I put back the original spings = problem solved ! ... No more vibration at low and high speed. So I figure out that that AWD model cannot be lowered. Or if tere is a way or a fix, please share it with me ! :)

Recently my 2008 IS250 AWD have a shaking problem. From start to 15-20 miles, front is shaking (from side to side). You can feel it in the floor and steering wheel. At high speed (55-75 miles) front shaking is back again. When gas pedal is release : it stops !... tire pressure = check ... Wheel balance and shape = check ... Does anyone ever have or know this problem ? Thanks, Al
