The suspension is very detailed, very intricate, and has some aspects I wasn't thrilled about. The first thing is the D24/D25 and D1/D2 pieces which don't fit perfectly well. The D24/D25 ones especially have a nasty gap around the base that fits into the hull that will be a pain to fill, even with Mr Putty and an acetone wipe. D1/D2 are these little boxes that overhang depressed areas and they want to sit at a slant, which will block other parts if you let them. Finally, the D39 parts are a pain to fit, as they have slightly offset pins and its not immediately obvious until you test fit them which orientation they are supposed to be in. This is problematic for the rearmost one on both sides as the pins don't quite fit without a lot of force but, since its difficult to figure out their orientation, I was nervous that I was forcing them into the wrong holes. Finally, these pieces have a trap set into them because they tell you to glue small articulating arms into these pieces before placing them on the model. Don't do this! What you don't din out until the next step is that these small arms fit into three of the roadwheel arms per side. Since there are no locating tabs to lock the orientation and you're doing it by eye, chances are they won't meet up properly. Leave those off until you get the suspension arms placed and then you can pop them into place quite easily.
