Default Thumping noise from 99 prelude

I have a 99 prelude and I here a thumping noise when I accelerate.. Mostly when I go uphill.. It comes and goes so sometimes it thumps and sometimes it doesn't. I got the front tires balanced but I don't think it's them because my steering wheel doesn't shake.. The rear tires were balanced about 3000 miles ago.. Maybe a weight might of fallen off the rears.. Also you can feel the thumping through my gas pedal slightly. I'm running 4 s2000 fronts on the car.. Tires have like 80% on rear and 50% on front.. Lowered on skunk2 slip ons running stock shocks..the thumping is faster as I speed up no matter the rpm.. It usually happens between 2500-4000 rpm but goes away after that... Running a stock h23 vtec blue top.. Does not shake at idle... Thanks in advance!

Replace the radius rod bushings if you have'nt done so. I think it's four of them, retails for about $20 a piece.

You wish this actually meant something but rubber wears with age and weather.

Senor' I have done did a whole lot. It's not about how many miles on the car? Instead, it's how the original units were designed in comparison to the newer ones, from Honda?
Thank you very much!

tried changing out the rear tires cuz i couldn't really identify where is was coming from all tires are balanced and it's still doing it but sounds like it's from the front passenger.. I tried shaking my motor but no budge although I don't know how you check a mount...
