Stillen HR S/C
They look smaller then I pictured in my head. I got 13" front/rear so I would have more wheel options for later. For some reason I change wheels a lot...Auto ADD I guess.
I had XXR 521 18x10.5 +25 up front and I had to buy thin nuts for the fake 2 peice fasteners to clear the caliper from the bolts that I also had to shave down, but after I did that I never had a problem and they looked awesome inside that wheel
Please excuse the rims, but it shows how my wilwoods filled out an 18

This should be the last power upgrade for a while. Here are the comparison dynos.
Last Year: Filters, TP, 3" Exhaust, No Tune VS. Same + Uprev.

Most Recent: Stillen HR S/C (SCi @ 49K RPMs), Meth, and JTran Tune VS. Same + Cog pulleys (SCi @ 56K RPMs).

All comparisons should be apples to apples. Hot motor, hot temps, Texas July, same dyno.
EDIT: The run with the cog pulley was cut short do to the belt trying to walk off the cogs. My current idler pulley is 3" OD, and the lip had to be shaved down some for clearance. Now the belt is trying to walk over the lip at high rpms. A 2.5" OD Lipped idler pulley is being machined right now to solve the problem. Then next week we will be able to see a full run with the new setup and a cleaned-up tune.

Oh yeah, and the bad news. My 305mm R888s still did not fit after the fender roll, so I'm selling all four including the 235 fronts. I had to order a set of Nitto NT-05s in 275/245.

Dont get me wrong. It can be done on my car too. But, I don't see any point in running so much negative camber that I end up with a 305mm tire making only 100mm of contact with the asphalt. I bought the wrong offset wheel to be running such a wide tire. It would be completely non-functional. Might look cool, but not worth ruining a set of tires. With a 275mm tire, hopefully I'll get a 275mm contact patch and good tread life.

Nice torque gain! Fitting big tires on the Z is all about correct width and offset, I don't know what your wheel offset and width is but a 305 is very possible but a tight fit, and I do believe a R888 is a wider tire compared to others
