I just got this vehicle last month. It's great on my potholed roads that surround my house like a mine field, arg! I have to have a flexible suspension to deal with these roads, downtown Dallas, TX. So bigger rims is not really an option.

It was going great until my first roadtrip this week. I was fully loaded, 2 people, full boot with no extra space, it barely fit, hanging clothes all the way across the backseat. Going 80mph in a straight line on the highway is not a problem, but some of the more aggressive highway curves made me uncomfortable going even 75mph, which is the speed limit minimum,

I like a little give in the suspension but I think the extra weight made my vehicle sway more than usual on highway dips. So, I want to minimize the excessive body roll, and sway, and/or bouncy boat feel, without losing the pothole road armor, that keeps me comfortable around my neighborhood.

Should I replace the rear shocks with KYB "OEM" style? Would this give me a slightly stiffer rear end? No one has mentioned this idea yet. (Originally I looked for Bilstein but they don't make shocks for this vehicle.) This is my preference to start. I will say that I test drove an F Sport Rx350, and did not like the suspension for my neighborhood, it jarred me too much, so I need something in between.

I like the idea of wheel spacers to give me a wider stance. Or I could drop the vehicle with Zoom Bane springs, maybe 1" or 2". I probably don't want to do larger sway bars, in fact I would remove them completely like a jeep crawler, but I might completely fly off the highway at 80mph. I will also consider the "body damper" that Dolphin installed, it sounded like Dolphin really liked that upgrade. My old 1998 Chevy C1500 truck benefited a lot from being lowered, but it was hell around the neighborhood, before and after the lowering.
I couldn't help but notice, and I don't mean this to sound rude, but you're talking about all of these suspension mods and you haven't even determined what tires you have. Personally I would start there, and I say this as someone who had had (3) different sets of tires on my RX (18's). I noticed quite a difference in handling between them, and it wasn't wear-related because I swapped out one set after only a month. You shouldn't be uncomfortable on a highway curve at 75 mph, especially with 19's.
