You are correct. It's been just long enough for me to forget these details. I have the 5.3's in the front and the 7.0's in the rear. I take it you don't think I'll experience that bounciness you're experiencing on the street?

I'd love to avert having this upon my first drive after installation.

it's hard to say whether you'll feel it or not. you're at an 8.2% differential with those spring rates. ideally, you'd want a slightly stiffer rear or a slightly softer front. if you want to be positive these harmonic issues won't affect you, trade your rear springs for something in the 7.5 mm/kg region.

I just checked the box and my paperwork. The ones they sent me to replace the 9kgs are 7.2kg. As it stands, my setup will be:

Front: 10.5-205 (stamped on the springs) = 5.3kg
Rear: 11-180 (stamped on the springs) = 7.2kg

I also read through all the PDF's you posted for the install while eating my lunch at my desk. Very, very helpful. Thanks so much!

are the 11-180's 7.2? they told me 7.0....

anyway, your rear frequency should be 9.7% higher than front. this is borderline; it's your call.

I asked him to double check his calculations and he said it was 7.2kg.
