    Tapout CT4BW Lowering springs installed

    I'd agree, I'm not sure there's any benefit to be had handling wise on these cars from lowering springs. Almost purely aesthetic, which I'm content with. It does feel more stable at speed though, which is an added benefit, but that could also be due to the more aggressive camber.

    Tapout CT4BW Lowering springs installed

    It's a tiny bit stiffer. It definitely feels more confident at high speeds. A few months ago I complained that the car felt a little floaty near the top of 5th gear. I don't have that Still very pleased with the setup. I may have opted to go 1/2" lower, but that's just personal preference and...

    CT4BW Jb4 w/ tap out bolt ons (dyno)

    I think for people looking to improve the Blackwing experience, 525whp like this is about right. If you want to slay tires and bang out some killer 60-130s, it's going to need more.

    What did you do to your Blackwing today?

    I dyno'ed it with the jb4 and a handful of tapout bolt ons.

    CT4BW Jb4 w/ tap out bolt ons (dyno)

    So both runs are done with all the same bolt on parts. Tapout Fuel cam, tapout air filters, tapout test pipes, tapout gig's throttle body and colder plugs. Baseline was done in slightly warmer weather, but this dyno is notorious for reading low. LF4's' should average around 410-420whp stock...

    CT4 BW BC Forged 19s

    there's 25mm in an inch, so figure half of that goes to the offset. So a +45 on a 10.5j would be like +35 on a 9.5j

    CT4 BW BC Forged 19s

    +45 on the back with a 10.5 is pretty low offset for these cars. Is there a +50 option?

    Blackwing Shirts available on Blipshift

    Really love the shirt. I see the power gains on the blipshift stickers have gone up too. Used to only be +5hp 😆

    Blackwing Shirts available on Blipshift

    their shirt material is really really nice quality. comfortable and well fitted. I love a TON of their designs, but they always print them pretty small on the shirts. If they scaled up the size by 50% I'd probably have bought dozens of their shirts.
