For more power for buck there's sterling's carburetors http://sterlingmetalworks.com/smw_services.htm I'm rebuilding my carb with his guide, and have heard great things about his carbs.
And for suspension, kentetsu linked me to his post when I asked the same question. He has a lot of good info https://www.rx7club.com//showpost.php?p=9096540&postcount=9 he has practically eliminated all body roll!

 

I like it alot more than I thought I would. I'm a purist who would normally hate rims like that or an over the top colour like that but man, that looks clean as hell brother.

And you'll notice a pretty big bump in power going to a header. It helps quite a bit.

 

Love the wheels, love the paint - you might think about painting the black molding the same as your body color and then putting them on?

thinking about the respeed coil overs anyone here running that set up

 

I have them on my 79 . They are awesome . Lowered about 1.5 " and race / street springs 200 Front , 125 rear . Its like a roller coaster ride around corners

talk to Joe or Dan at RPM motorsports in Breslau Ontario, they are the canadian supplier for ReSpeed

 

It looks clean. Not much on the spoke design on the wheels, but if you like them that's all that matters. A header will add a bit of power, but more over it will change the sound.

 

Thanks for all of the input guys. Will add more pictures in the next couple of days. Have a great summer.
