Super-Easy Track Prep

Jun 11, 2013 update to the Nissan 240SX project car

Before heading to Sebring, we had some servicing to do.

Considering the car’s age, no issues were spotted during our initial service. So, is it up for some laps at Sebring?

Sure, you can easily spend a lifetime building the ultimate track car—CAD-CAM work, wind tunnel time, lots of consultants in white lab coats. Or you can do it the down and dirty way.

Exactly week after this one-owner 1991 Nissan 240SX joined our fleet, we took it to Sebring International Raceway for an SCCA PDX track event on the shorter Club Course.

Even though we were short on time, we didn’t totally skimp on prep. First we ordered some Hawk HP Plus brake pads from the Tire Rack. They had these track-capable pads in stock. We also flushed the system.

Next, an oil change. Based on a recommendation from a friend at the company, we refilled the sump with 10w-40 synthetic oil from Red Line Oil.

Finally, we needed fresh tires—the ones on the car were simply past their expiration date. We had a fresh set of Nitto NT01 track tires on hand as well—it’s a great track tire that can also survive the drive to the event.

Their 205/50R15 size would knock an inch from our outside overall diameter. Yes, that would lower our gearing—nice for a car that’s not sporting a ton of power—but we’d also sacrifice some load capacity. Consider this a stop-gap move until we can order the correct wheels and tires.

Considering the car’s age, no issues were spotted during our initial service. So, is it up for some laps at Sebring?

load capacity?

Technically the smaller Nitto tire can support less load than the larger OE-sized tire. It's just one of those things we need to mention and be aware of.
