Just felt with Rod Summers from Z1 motorsports and purchased the 400HP package for my G37s. They were very polite and helpful with all the questions and concerns i had. Would recommend dealing with them for sure

I ordered my engine underbody aluminum splash shield from them and they're an all around great company/vendor to work with for sure.

I ordered the Akebono NS (non 6 MT) BBK for my 2011 G37x a few weeks ago. Red Infiniti calipers got me wondering what kind of 20's should I replace these stock 18's with?! Z1 is super helpful and SUPER available for any and all questions. I cannot say the same for Rock Auto (first off what an archaic system!). At least with Z1 I can call and talk to a human who can sit and really trouble shoot with me! The 2x 5mm spacers for the front end (which was ordered as per their suggestion ) allowed me to install this seemingly too big BBK into the stock rims/wheel setup.

I know most of you have had good experences wirh Z1, that is wht I went to them. Unfortunately mine was not, I triwd to order a 1.3 bar radiator cap callwd rhem on friday. The following wednesday and 7 phone calls later I had to cancel the order because despite following the links they sent me it continued to not show an order oe let me enter one. The people were polite but I could not order the item. I have ordered parts frim many sites..dealers, internet, and etc qirhout a sungle hitch. Rhwt need ro srwp up the game.

That's unfortunate @BIL2
I have used Z1 and CZP for years and both seem to offer top notch service with very fair pricing (30% below the dealer on OEM parts).

Same experience, although sometimes the tech assumes I'm a moron and I have to talk them through to the point where I was a professional mechanic before grad school.

I feel that way sometimes as well when I talk to them as you need to get passed the "have you tried turning the PC off then on again" stage.

In their defense, they likely field alot of calls from people trying to make cheap, reliable, power.

As the wise man once said, you can only have two of those.
