So the old all season tires on our Project DC2 Integra were so bad that amazingly, modifying the suspension and adding an LSD did little to improve the cars lap times! All the suspension work was nullified by the old non-performance tires. To make the most of our car’s suspension and new brakes we had to drastically upgrade with a set of Rays Gram Lights wheels from Mackin Industries and some NT01 tires from Nitto Tire to wrap them in.
For wheels, we selected the Rays Gram Lights 57Transcend in Super Dark Gunmetal. Not only is this a cool color for the white DC2 but the color will hide brake dust since Jeff is lazy and never cleans anything. The finish is Rays corrosion resistant multi-step powdercoat which we find to be very durable.
The Gram Lights 57Transcend is a high-quality high pressure die cast wheel. High-pressure die casting eliminates the porosity, gas bubbles and other internal flaws that typical gravity cast wheels can exhibit. The process also gives better grain refinement. After casting the wheels are heat treated for additional increases in strength. All of these measures give us a wheel that is decently light and stronger than your typical cast wheel. Since we wanted to run a bigger tire, we went to a 15×8″ wheel with a 35mm offset. This is quite a bit up from the stock 15×6″ with a 45mm offset. The wheels weighed in at 13.6 lbs, not feather light but a respectable weight.
The Gram Lights 57Transcend easily cleared our bigger 4-piston Stoptech caliper and 290mm rotor with no issues. This means that it will also clear most big brake kits that are designed to fit inside 15″ wheels.
The stock sized tires were some wimpy 195/55-15 all season cheapo tires. We had to get something a lot better. Something better was a 225/50-15 Nitto NT01. This is a significantly larger tire with a lot of grip. The NT01 is a competition tire that is DOT approved making it street legal. Although the NT01 is a soft compound tire meant for racing in classes that require a DOT tire, the NT01 has a reasonable UTQG treadwear rating of 100 and is very durable and can endure many heat cycles without losing significant grip. We have gotten more than 20,000 street miles on NT01’s before and as many as 4 complete race weekends from a set making them superb dual purpose track/street tires.
