  1. Time to share with your friend that's a cheap ass. this is his/her time to shine. With the new arrival of the 48" V2 miata street wang, We are Blowing out the remaining inventory of our V1 Street wangs. -limited supply. -Big BIG discount -They are in stock Discount code - V1streetwangblowout If the code doesn't work they are sold out. https://9livesracing.com/discount/V1streetwangblowout...
  2. Just a Big FYI upgraded endplates and Dual elements now ship free. https://9livesracing.com/collections/all/products/the-mega-12x10-75-end-plates
  3. NC guys the medium downforce is here. our testers reported back 3 second a lap drop. and an addition of over 300% more downforce. Kit now comes with our Stronger V2 style pylons. https://9livesracing.com/collections/all/products/copy-of-miata-medium-downforce-kit-90-05-na-nb
  4. It's a airfoil made by Elan for the champ car projects. so there isn't a actual profile number to reference. if you shoot me over a email to Johnny@9livesracing.com i'll be happy to shoot over the information we have. if it's for a miata/ corvette we have opensource CFD info on how it behaves.
  5. That depends really. we where testing diffusors quite alot of diffusor set ups and it all depends on what's up stream.
  6. The more the better I would think. I asked the guys to do some CFD testing with brake fans, to see if cheap fans would have a noticeable difference. then covid hit and we became super busy.
  7. moring racers. Wanted to share our newest venture. the low downforce kit for miata. Basically this is for super speedway tracks. Daytona/Charlotte. where drag is KING. balances with a Air dam and our 40" wing. more info here https://9livesracing.com/collections/all/products/9lr-low-down-force-kit-for-na-nb-miata
  8. answered. sorry don't check pm's here regularly. We try to pop in once a week but it's not always me that's popping in. it's best to send a email to info@9livesracing.com
  9. calculus was explained to me as a "how close you can get to an object without actually touching it". splitters' performance could be explained in the same way. closer to the ground the better it will work, right up to the point it touches the ground and then it stops working all together. so get it close but if it's too close it will purpose. aka bounce off the ground as it goes from Downforce, to stall rapidly. the perfect height depends on your splitter, tire and suspension combinations, just keep it off the ground.
  10. i love your ramps. What's the cross weight? ideally we want to have the aero load = to the chassis cross weight. The splitter looks effective like it could be making a real amount of downforce. without anything in the back the rear is going to make lift. meaning as you go faster the front will be pressed down and the rear being pulled up. on slow tracks it might not an issue. but on the faster ones the car could become dangerous to drive. one of those things that's not a real problem, until it is. that being said with a heavy front weight bias you won't need much downforce in the rear to bring a balance. We where seeing 55" wangs working well at a low aoa on FWD car. we even won the highly competitive Honda challenge class with that exact set up on an integra. and about adding drag our 70" wing @ 0*aoa only requires 2.2hp to move 100mph. a 55" wang would be <2hp
  11. Ready for black friday? https://9livesracing.com/account/login sign up for the news letter to get the details. We promise to not spam. our internet guy is lazy.
