Your past posts have all indicated some type of "hooning" on the street, i.e. aggressive/immature exhibitions of speed. You went and stated that you wanted more power to reach a higher top speed, then that you were doing this in Mexico??? You then reportedly twin turbo and then this thread pops up. You were then called out for your aforementioned questionable exhibits of speed and power, to only say "ok im going to the track, what about 305 45 17 et street R on 10x17 +18 enkei rpf1?" and "All i want to know is can you put ET street R on rpf1".

You have not answered the question on what gbrettin asked, Drag strip or Track? A valid question that has a lot of value, pending your response on intended usage on which type of track. If you are doing say time attack, you do not want to use a drag slick. If you are doing a drag race, you do not wanna use a track based tire that is intended for load shifts as a result of navigating chicanes.

Optically speaking, if your past posts shine any light on your true intentions for your Z, and I don't mean to speak for everyone here, but please take this somewhere else. Either another forum or a FB group or some other type of social interaction. I feel confident in saying that a majority or the community here does not want anything to do with street racing.

nm. You mentioned 650whp.

Get some 15's that can support 275 drag radials. You will need to do a base break conversion to accommodate that. You will also need to get shocks to support the independent rear suspension. Call Import Drag Solutions. They will take in the weight of your car and custom make you an order to support a range of whp. The shocks will be about 1,000.

"What's a bead lock?"

His understanding of how a car works is simplistically str8 forward...every "problem" he had, the answer was to change to a different part. He thinks "buy a new part = fix a problem".

Stop wasting time.

You could do a known good 17" to clear and bead lock it for drag radials. It will be more expensive wheel and tire combo; however, I did exactly just that. As an example, I had beadlocks put on the Nismo 57cr wheel by Mac Fab. Keep in mind this setup will not work as well as a 15, but I have future plans for that. I'm going to make a drag pack brake kit utilizing TBM brakes.

Note that you can't run the same setup as what I have. My car's electronics, or lack of, is different than yours. I'm showing it as an example of custom beadlocks. You will need to do some math to figure out the rotational differences. I believe it needs to be with-in 3% for OEM. There's web sites for that.

Also, you can not drive your car if it is damp or raining. If you run over spit on the road you might spin out. It's meant for driving to the drag strip, legal enough to get you there.

I'm offering up this information in confidence that you are intending to hit the dragstrip btw. Of which, I have a nagging feeling you are not.
