Rear end change

You don't need a 4 link for your intended purpose, heck, you probably don't need super stock springs! Most racers I know don't have a 4 link and do just fine without them! Spend your money wisely grasshopper, don't buy on someone else's recommendation, build your car for what you want to do!! For around town, 4-10's are OK, but they are on the low side for any other street driving!
