I picked up my Boxster S from my shop Thursday afternoon. Had my leaking water pump replaced, oil changed and brake fluid flushed. They also added a Mantis deep sump and stainless steel flexible brake lines and installed the underdrive pulley I had bought late last year. This is the first time I drove the car since I had the ROW M030 suspension kit installed in January and had my 18 inch wheels on. It definitely feels tighter with the ROW M030 and the 18 inch wheels than it does with 17 inch wheels. The brake pedal also feels firmer with the stainless steel lines, but that may just be psychological and not real. As for the under drive pulley, the engine seems to rev a tiny bit faster, but again that may be in my head.
Today I washed the car. Going around and washing door jambs and trunk edges, I noticed that my car does in fact have the LN Engineering IMSB upgrade sticker. I knew I had the single row pro installed, but never knew to look for the sticker until I read about it here!
Next week is HPDE at New Jersey Motorsports Park Thunderbolt, looking forward to it!
