With these cars, if you're not going to be racing the car hard, I would stick with the rubber bushings that come with the four link. For street driving, the rubber bushings are much quieter and solid enough to still make the car handle extremely well. If you're looking for a full on race car, we have an option for the bars to be built with heim joints on both ends. The heim joints that we use are a kevlar lined joint and do stay much tighter and quieter than others than most of the other brands on the market. You may notice an increase in the NVH in a newer car that is well insulated but in a hotrod or heavily modified car, the noise transfer won't be noticed as much.
On a rear sway bar, we don't offer one for a couple of reasons. One of the biggest reasons is space constriction, there isn't alot of room left to run one. Unless you're running a big tire, the need for a rear sway bar isn't really needed. We've had a couple of these cars here as test mules. The results that we received were great on the street and on the track!
