    Girodisc Rotors - any takers?

    Here is the response I got from their rep: “ Based on the rotor weights I’m finding online and knowing what pad the 380x34mm front rotor uses, I can make an educated guess that we will be able to pull 3-4 lbs out of each front rotor. The rear rotor is proving a bit more difficult – we don’t...

    Girodisc Rotors - any takers?

    All very good questions. I sent them to the rep. I’ll try to answer based on my experience : the weight savings for the 4BW won’t be so big, my guess 1-2 lb per corner. I’m waiting to get the confirmed data of how much saving the 1LE Camaro got. Yes, stock rotors are suitable for track use...

    Girodisc Rotors - any takers?

    Hi everybody, I've been in touch with a Girodisc rep regarding development of front rotors for the 4BW. For those of you that don't know Girodisc manufactures in the USA top notch 2 piece rotors for track (and street) use. Usually you will see some weight savings over stock rotors + their metal...

    Driving Shoes Recommendations

    I learned the hard way that everybody has a different foot. Most driving shoes are very narrow. I have a very wide toe box. The good thing is that the Black Wing pedals are not too close together, so narrow shoe isn’t a must. I’m using these days a Puma shoe. I’ve ordered is half a size bigger...

    4BW Track Weekend – the Good, the Bad and the Ugly (with Video)

    Two notes: 1. I daily drove with the track alignment for a few weeks after my track event. After going back to stock alignment I realized how much the daily driving is more comfortable. The suspension absorbs bumps way better and steering wandering is gone on a ‘bad’ road. 2. It looks like we...

    4BW Track Weekend – the Good, the Bad and the Ugly (with Video)

    As noted above: I confirmed with a tech from Girodisc that the front pads of the 4BW are the same as 6 gen 1LE or C7 Z06. As for the rear pads, I think ( but cannot confirm) that they are the rears of 6 Gen ZL1

    Jacking up your Blackwing

    Looking forward to your feedback. That’s the downside of having a special limited number car - less incentive for aftermarket. We need to start a petition for Girodisc to create 4+5 BW rotors !

    CT4-V Perf impact of sunroof?

    Sun roof is about 50 lb and less head room. I wouldn’t be worried about lap times, but it’s naturally more toll on the brakes and tires at the track. The car is already consuming brakes like crazy. I personally would avoid it if possible.

    No Lift Shift Question

    Dump it. The whole point is fast acceleration. Hence the car is a little unsettled. No issues if you are tracking out in a straight line.

    No Lift Shift Question

    No lift shift is a great feature for track driving. You are tracking out of a corner in 3rd and there’s a straightaway where you bang it into 4th. You have to be really close to redline before the shift. It’s better to do it in a straight line, as it sometimes unsettles the car. I wouldn’t...

    Rear Diff Fluid

    At the beginning of this thread (post #12) I posted a printout that I got from the dealer. Only one of the options had E LSD. That’s what I used. Filled 1.3 qt. No issues ( yet ) one month later

    Rear Diff Fluid

    I've never heard of the passenger's side fluid. I does not mean that I'm not wrong. Haven't heard about it in the Camaro world as well. Also, the fluid number that I used for the rear diff was 19418501. Different number for 5BW. I followed the owners manual and added 1.3 qt (not 1.6 as this doc...

    Rear Diff Fluid

    Look at my pic above ( with the orange glove). The bottom plug is for drain. The one above it is for filling.

    Rear Diff Fluid

    I know it’s similar, but I used 14mm hex socket. Direct fit to my 4BW.
