IRS Disc Brake options with a wide 5 bolt pattern.
First off, the car this well be going on is a non fender flared Porsche speedster replica with IRS. I'm not a Porsche purist, although I would like to retain the lines of body. The look I'm going for is an old school hot rod. With that said, as of now mocked up with a 1963 bus drum machined to fit a IRS axle, while retaining the stock drum face offset, and using
http://www.csp-shop.de 7"x15" Centerlines w/4.375" of back spacing, along with
http://www.blindchickenracing.com/ 1.5" Narrowed IRS Trailing arms, and running a 205-50-15 tire, this fits without bastardizing the fenders around the wheel well area. If you haven't noticed I'm a hater of fender flares, they imply after thought to me!
Now for my questions: Out of the Disc brake companies that are out their, is their one that I'm missing or over looked that makes a set of brakes with the following spec's? Wide 5 bolt pattern, Stock offset or at least within a 0.125", Forged aluminum hub with machine finish, Steel spline section and Emergency brake hook up?
This list of observations and opinions are sarcastic. So understand, I don't like the taste of my own foot, but I've put it in my mouth on occasion. As with opinions.., their just that.
www.cncbrakes.com Series 664 looked aesthetically the best, and they claimed that their 7075 all aluminum hub would withstand the rigors of daily abuse without stripping the splines. But the down side was they had to much offset from stock. (* With Aluminum Calipers, this brake and Tatums are neck and neck for the lightest set ups).
www.nealpedals.com 66-538D Offset to much. On the plus side, it had an emergency brake.
www.tatums.com Brake Kit #104 appealed for a couple of reasons. The vented hub, very light and they also claimed that their 7075 all aluminum hubs had been on their 400hp sand dragster for three seasons with no spline problems, in addition these guys made these brakes with the look in mind.., but the down side they had +0.7" offset from stock, and no Emergency brake provision. This would have been a contender. (*)
www.cbperformance.com CB's Rear Wide5 disc brakes. Well..., they got most of it right. Structurally, I know the cast aluminum hubs with steel splines are just fine for the street, the problem I have comes in that cast aluminum doesn't hold as nice of an aesthetic pleasing finish that forged does. I also have mixed emotions about the look of these. The convex surface, reminds me of hip-hugger jeans on a fat chick, "Muffin top syndrome". They don't have the nostalgic look I'm looking for either, but they well fit.
jamarperformance.com # DBB204BB Unfortunately they only have off-road stuff. Offset to much.
www.gear-one.com G1-2400 Unfortunately they only have off-road stuff too, and offset to much as well.
www.csp-shop.de # 599 168 5205S, of these brakes, CSP's would have been my choice, had it not been for that after thought in the 6 bolts in the middle of a 5 bolt hub. Talk about ruining a nice effort, they got the finish, offset and spline section right. Man' you can read between the lines on this one..., Their management got a great deal on 6 bolt discs and told the machinist to make then fit. If at all possible, I'd like what shows not to scream after thought!
If this is the complete list..., I know buying a set of brakes that's a shelf item would be far cheaper than having a set made. So would you guys/gals post some pics of the rear wheel assemblies or your rigs with hub caps off if running stock wheels, and wheels off all together if not. Seeing the drums helps make anybodies mind up that's close to spending the money and this will help to make my mind up as to buying CB's bubble drums or the after thoughts.
If you've done this conversion, I'd love to hear from you. Thanks, David
