    Installing a Racing Harness (Belts) and Harness Bar in a Boss 302

    I don’t see any issue with using a HANS style FHR with them. They have done their own sled testing, ands found they worked well. But I can see an issue of you are in a group that has rules requiring an SFI or FIA compliance FHR setup, because the Schroth Quick Fit Pro doesn’t have that...

    Installing a Racing Harness (Belts) and Harness Bar in a Boss 302

    Agreed. I’ve always approached the Quick Fit Pro question at tech from this perspective - they are a FMVSS209 approved OEM seatbelt replacement, not a safety harness. For me, the benefit is there is no expiry date for them. Just watch for chafing on there early S197 headrest posts - the notches...

    Rear end gear ratios - anyone have a calculator spread sheet for looking at speeds?

    Thanks Blacksheep. That’s great! After some review of the spreadsheet and my min/max corner speeds, I think I’ve finally decided on the FRP 4.10 gear set and their rebuild kit for the diff clutches. As much of a pain as it will be to pull the rear end completely out of the car, I think you are...

    Rear end gear ratios - anyone have a calculator spread sheet for looking at speeds?

    Yes. I’ll be doing a full setup on it. I’ve got some experienced local help here, but it’s worth noting for anyone else not familiar with setting up new rear end gears that there is way more to it than just unbolting and reinstalling the parts. I need to refurb the diff clutches as well due to...

    Rear end gear ratios - anyone have a calculator spread sheet for looking at speeds?

    Thanks. I’ve found a couple online since I posted. I’m going to build a spread sheet from there I think unless someone has one already built.

    Rear end gear ratios - anyone have a calculator spread sheet for looking at speeds?

    So I’m about to order a new set of rear gear and pinion. The current 3.55 ratio is too long for my track- on a warm day, I’m in 3rd for all except one slow speed corner in 2nd. So I’m hoping to look at where my RPMs are going to be at my current apex speeds with different gear sets. Have any of...

    Brake lines for S550 4 piston caliper swap

    Mostly cost and availability. The Boss 302 calipers aren’t as cheap as the base GT calipers on the s550, and given their uniqueness, pads are harder to find in my part of Canada. But I can always get base model S550 stuff here. And they are pretty much a bolt on fit, just need you adjust the...

    Brake lines for S550 4 piston caliper swap

    I’ve looked through lots of threads but can’t seem to find my answer. I’m gathering parts for the brake swap on my 07 GT to the base S550 4 piston calipers with the 14” GT500 rotors, and I’m not having any luck figuring out which stainless brake line kit I should order. Any suggestions? Pic...

    Pics of your Boss 302 or S197 Mustang at the track!

    It really is something I’m truly grateful to be able to share with him. He’s done 2 track days, and he’s only 2.8 seconds behind me. I had the opportunity today to be in the car during his first 4 wheel off, in the same turn making the same mistake that I made. Except I hit the concrete wall...

    Pics of your Boss 302 or S197 Mustang at the track!

    I spent Friday, Saturday and Sunday at my local track, Atlantic Motorsport Park here in Nova Scotia. My son did his lapping school (our region issues licenses for Lapping and Time Attack participants) and I ran 5 sessions myself. Today was regional race day, and our regular Safety Car driver...

    200 tread wear tires

    I’m truly hoping the ECF becomes available next year in Canada. Freight fees from the land of the Bald Eagle send the price up quite a bit.

    First-Timer Thread

    This has been my 17yo son's first full season in autocross. He's also signed up for the local PCA HDPE school in a few weeks. Two weeks ago we got to run at the Canadian Nationals in PEI.We ran a slalom/skid school on the Friday, and he got the hang of the car pretty well. Once he was able to...

    Brake Pad/Rotor Upgrade for track days

    So, I started by running the stock pads and 2 piston rotors, and while that may take someone through a school event or a lazy track day, I killed them in a day, as I completely expected.I run a set of 275 wide Conti ExtremeContact Sport tires - relevant as braking and traction work together...
