The 240SX/Silvia is an amazing platform in all it s generations. The FR-Drive train and it s light weight offer a perfect balance between speed and agility. Used in a wide range of motor sports such as drag, drift, autocross, road race and even rally the 240SX has proven it s worth time and time again. As a street car, it s refined and well mannered, comfortable to drive in and stylish with a bit of aggression in it s curves. Although it s initial design was sporty and aggressive it was still designed as a street car. Those who seek the most from their car know that in the rigors of competition you need to extract every ounce of performance from your machine. You need the capability to have every degree of adjustment above and beyond that of a street driven vehicle. You need the strength to withstands the stresses and strains of hard corners, a rough course and brutal weight transfer and chassis flex. It s within this understanding that Megan Racing has unveiled our line of reinforced suspension arms that offer the strength and adjustment that any competition vehicle will ever need. Constructed of high-strength steel alloys that offer durability, strength and yet remain light-weight, these control arms have been track tested for months in road race, autocross and drift events to assure quality and performance. These rear upper control arms available for the S13 and S14 chassis are an excellent upgrade. With it s adjust ability you are able to carefully tune the vehicle s Rear-Camber to your specifications. The pillow-ball ends replace the stock rubber bushings on the chassis and offers you a more direct and predictable feel that you require in competition. With proper adjustment will allow the adjustment of proper camber which can greatly effect tire wear and performance. The adjust ability and feel is also backed with the comfort that your stock thin tension rods are now replaced with thick steel constructed arms that can withstand the stresses of competition. Rear upper control arms: Used to adjust static camber. The actual arc these move in is the camber curve, but keep in mind that all of the rear arms help determine this. They also help determine roll center, similar to a double wishbone setup. - Will fit Nissan 89-94 240SX (S13). - Adjustable lengths to tune Rear-Camber - Pillow ball bearing replaces OEM rubber bushing. - Durable Steel construction to withstand high-stresses of competition. - Powder coated with brilliant blue finish for years of performance.
