Super Lap Battle is the largest Time Attack event in North America and the preparation is just as large. For instance you could easily say that it took from SLB 2014 til SLB 2015 for my STI to be prepped for this event… Or you could say that we made so many changes and ran into about every obstacle possible going through the build we thought would be completed in just a few short months and it turn into a year. This volume of articles will cover the struggle that was our build out from the 2015 season or event as it turned out.

We also were prepping to bring the car back to Pierce Motorsports and have him add on to our cage as Mod/Limited then allows for more additions that will help with ridgity.

The motor needed to come out as well for a check up. It was a very good thing that we did this being what we found… All four of our rods had been bent and the cylinder bores had been damaged. If we did not break 5th gear during super lap battle and tried to run Redline Time Attack ACS Roval the likelyhood of a catastrophic failure was very high.

We started with great optimism and tons of pizza working on changing our dominant street class car into a dominant Mod/Limited class car. This process involved cutting weight on the car as much as possible, adding larger and more aero components, and why not add more power! Now when I saw that doesn’t it sound like a weekend or so worth of work? HAHA boy when you start to really write out this list of items to be accomplished it really begins to take on a new meaning.

We had to tube the front of the ar being how much rubbing that kept occurring throughout the last 2 years, although we were going to be pushing the wheels and tires out wider with a different offset and flares we decided at this time it would be better safe than sorry.

We began with the items that would cost the least, which is busting out the sawzall, grinder and drill and taking off anything and everything that we didn’t need. This is where things can get a little tricky, you are making decisions that could easily cost you more work later on if you are wrong so keep in mind we always thought about it quite a bit before cutting. Although I must admit this is the part that I particularly excel at especially the part where you get to cut and hammer. Along with cutting weight with metal reduction Gil and Oscar also went to town working on the wiring harness cutting out any unused wires and connectors.

Most people would run very very far from this task but Gil and Oscar jumped on it and worked through the entire harness cutting off what we did not need.

The next item on our list was to install our new Fortune Auto Dreadnought Pro coil overs and then try to figure out how to fit our new Yokahama Advan RGIII wheels and more importantly 295 wide tires! As anyone with a GD Subaru knows fitting 255 or 265s are difficult so going wider than that is down right a pain in the ass. So I looking around and found some overfenders but being the company that made them were crap and wouldn’t back up their product. So I then had to buy another set but that was only after we made the attempt to make our own which really did not go very well.

We chose a set of Yokahama Advans wrapped in Hankook TDs.
Everyone got into the mix as cutting and hacking is a great stress reliever.

Next up we actually put something on the car!!!

After the amazing 2014 season the build for the 2015 season started instantly at Yimi Sport Tuning although first we had to fix what we broke at Super Lap Battle which was the transmission as it tends to be, although this time it was 5th gear instead of the usual 4th.

With the transmission pulled the decision then came to pull the motor and send it to Outfront Motorsports to evaluate the condition. An interesting piece of usual Forum talk is about the use of GSC cams and there wear on different items in the head. Lets just say that it appears to be just another form of some of the usual garbage that you find on the forums from guys that improperly installed or broke the new parts in. Now GSC Power Division is producing Billet cams for the EJ series motors as well as many more. My JE Pistons, Scat Crankshaft and JE Pro Seal head gaskets all looked perfect.

Now one of the largest upgrades the car will see is a larger set of wheels and tire and being that I wanted to use a set of wheels that will be able to withstand the abuse from berms and dropping tires which is why I called up Mackin Industries and got a set of 18×10.5 +25 Yokohama Advan RGIII’s. Besides the fact that they are astonishing to lay your eyes upon they are some of the strongest wheels available. They are going to allow for the use of tires ranging from 275-295.

The next big item to allow for more grip to be added was a set of the Fortune Auto Dreadnought Pro 2 way adjustable coilovers. We were lucky enough to team up with them and with their amazing product support, customer service and overall product we have high hopes for what these will give back to us. As well as new coilovers we installed a few other of the few Whiteline suspension products such as the rear anti-sway bar mount seen below.

Now before we could add anything we needed to take out some items to allow Pierce Motorsports to go through and add to our cage that they had done for us last year. One of the items was going ahead and doing the dash bar and connecting to the front suspension mounts. Now besides the cage we pulled the wiring harness out and did some custom cutting and pulled what we could off of it in efforts to get rid of some weight and complexity. Thinking oh just cutting some wires is easy right… yaaaa With all the wiring being cut we called up AEM Electronics for their AQ-1 Data logger and a slew of gauges which will help our understanding of what is going on in the motor as well as what our aero package is doing. We are just about finished with the installation with much more information coming on this. These AEM Electronics digital gauges are amazing and with the ability to be changed to whatever gauge you want (within reason such as oil temp to water temp) or switching the gauge faces from black to white. I would also imagine creating your own custom faces would be a very easy task. The wiring continues, and with everything tested out a permanent connector would then be applied.
