I'm currently using my G Coupe for a 200 mile+ commute a few times a week. Its 90% or more highway driving. I just installed wheels and the car needs lowered! I'm less concerned about overall performance as I am ride comfort and tire life.

So what drop do you guys suggest for best ride quality on the highway? I want to keep the alignment as close to OEM specs as possible. The wheel setup is 19x9.5 +20, and 19x11 +25. Tires are 245/35 and 285/30. I have NOT rolled the rear fenders, but do not object to doing that.

 

Nothing beats dialing in a quality set of coilovers, but if you're not ready to drop nearly a grand for that, the most common spring drop are the Tein S-Techs. A mild 1.2/.9" drop with spring rates that aren't too soft or bouncy, almost just right. You could look into the Eibach ProKit (1.1/1") but the spring rates tend to be a bit bouncy.

You will need to roll your rear fenders if you want to try to get within oem spec. Our cars don't have front camber adjustments, so if you want to get back to spec with either of those spring drops, you will need a front camber kit. If you don't want to drop ~$300 on a set, just make sure your alignment shop sets the toe as close to 0 as possible, and flip your tires every 3-5k. - Your rear camber MIGHT be able to get back into spec. There are several people who have been able to get back into spec with a 1" drop in the rear, but others haven't. You're best to invest in a rear camber kit, if anything, just in case, and for future suspension mods.

 

Thank you so much! This is exactly the info I was looking for.
