2003 G35 coupe 146k miles
Lowered

When I'm driving the car feels like there's a flat in the rear. It's a very strong sensation. I removed spacers and used different, known good wheels and tires, same thing. Doesn't make a difference if I'm in gear driving or coasting in neutral. Very very irritating issue as we get close to the end of the season.

 

Lowered on what?

 

Ohlins coilovers

 

Initially, I swapped other wheels on. Both rear bearings were beat, so I replaced them, put the known good wheels on and drove it, no issue. Put spacers and the bigger wheels back on and drove 8 miles, no issue. Stopped back at my garage, cleaned the car up, got 1/8th mile down the road and boom, all of a sudden the car feels like it has a flat. I pulled and tugged and checked all the suspension components when the car was apart for the bearings. I can rule out tires and wheels, as well as bearings. Axles looked and felt good as well.

 

Holy.

Have you adjusted the comp/rebound to your preference? Maybe it's maxed out in the wrong direction lol. So many Motos I've worked on where settings were whack.

 

Everything appears to be in order. I've never had an issue like this before. So it has me stumped
