Well it looks like 93 is the way to go and what most people use. Good to know.

Corney, here a few more pics. The body kit is from Extreme Dynamics or something like that. It fit great, and looks good too - atleast I think so

I thought it says premium recommended. Which is different than required. It's been awhile since I looked at mine but I thought it says something like it will run fine on 87 but with reduced performance or some crap like that.

Yup, my manual says that you can run regular, but performance may suffer.

I typically run mid-grade when I'm just running around town, etc since my normal day never involves going over 45. For highway trips I've been putting BP 93. It might be all in me head, but I swear I can hear a change in engine noise when I put 93 in.

Thanks for the complements Mgpeagle and Rick or is it Ted, lol, I appreciate it.

I have to get the zinc slotted and drilled brake kit for it to clean it up, but everything has come together and I absolutely love to drive this car, it's what makes me want to go to work every morning, hahahaha.

Looks great either way!
That's the razzi kit, iirc.

Oooops...didn't continue reading to see the pics. But yeah...Razzi. At first glance, I thought it was the Regency kit.

I used to love my car that much but now my recently rebuilt (1 month old) transmission is getting way too hot. I put a motorhome trans cooler in it and it still gets to 226 degrees when I arrive at work in the morning. What a joke!

You have a really nice car though.
