I know this is a oldschool car but i recently aquired a mint IRS rugrat with a ton of upgrades. I already know even though its old the parts support is still pretty good I was just wondering if anyone had any positives or negatives to say about this car versus newer chassis like the BMI, CRC gen x, or The 12R5. I did a search but alot of the posts are kind of old. Any input, advice, and tips would be greatly appreciated.
