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 is 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-Lower control arms are designed to replace the large OEM control arms in the back of the S13 chassis. By upgrading these arms, you will be removing the soft rubber bushings that are now aged by 12 years and are deteriorating with Pillow-ball joints that remove all play in the suspension. This allows energy to transfer more efficiently into your suspension components to give you a more predictable and consistent handling characteristics. The adjustable heim joint also allows you to change the overall length of the arm which will adjust both track-width and camber which can allow for a more wider tire-wheel combination as well as more efficient suspension geometry in the rear no matter what motor-sport you are competing in.
