Taking some weight out of EPPs LT1 project car




On the bottom left on the last pic you will see the caliper brackets. I will be working on the spindles today.

Saved 3.83 on the left side. Not really dangerous, the only thing you don't want to do is run these brakes on the street on a daily basis.

I talked to tech rep from Weld Racing, the Magnum PRO 1 piece 3.5" wheel only weighs 7.5 lbs. Combined with MT ET fronts you get a total tire/wheel weight of 20.5 lbs. My current 5.5" Weld XPs with MT Sportsman front runners weigh 32.6 lbs. I will save approximately 24 lbs. just in front wheels/tires. Guess what, my XPs from the front are now for sale!

Just a side note, I saved 5.00 lbs. on each rear rotor alone. That is alot of rotating mass! I am also going to delete all the emergency brake equipment and I am sure the aluminum spool is going to save alot. This reduction total also doesn't include the front wheels and tires I will be getting, another -24 or so. I ordered some aluminum intercooler tubing to replace some of ATI's steel, that will be weighed when done.

I sent the spindles to Jet Hot for coating, I'll get some pics of the finished front brake set up when done. With some new upper a-arms from BMR, this front end will look new again.
I had to order a different hat for the rear Wilwood brakes, the 12 bolt kit from Moser had a 2.81 offset and these f-bodys have a 2.66. I'll also get pics of these when done.
She is coming together and the engine should be running again this weekend. I would like to thank Josh at Procharger for sending some new tubing for my intercooler set up, changing things around to ATI's new piping.
Ultimate goal is in the 10s with this set up. I'll be happy to pull the engine to go faster then.
