You guys that lowered your cars, did you use the stock isolators, get the polyurethane isolators, or just leave them off for a lower drop? Whatever you did please let me know and how it came out. Post some pics if you can. That would be great.
If you have a 99-04 car...they should still be in good shape. I would reuse them.
I bought polys for my 91 notch when I replaced the LCA's because the stockers were rotted. I didn't notice any difference in the ride quality. I didn't take measurements either, but Im sure it sat up 1/8"-1/4" higher.
