Thanks Bob,

I stand corrected. I just remember Lynn saying there was a difference. It's only been 6 years since I bought them. I'm still as fast as I always thought I was too Regards, Matt

We shortened the pipes on 2045 slightly to tuck them up a little closer to the chassis, etc. If anything the primaries as they come from ERA are a little long to account for production tolerances, different motors/head combinationsand and motor-mounts. After all, it is much easier to cut a slightly too long pipe than have to add to a short one.

Jim

Jim, your car looks amazing. So you shortened the primary pipes where they attach to the headers? Your car also looks like it sits quite a bit lower than mine, or just the appearance because of the 15in wheels or is the ride height lower than the ERA suggested height?

John,

If I could I'd post a pic but I'm having a few problems with that. Jim's car sounds exactly how I did mine too. Send me your email again and I'll send you some pics. Regards, Matt

Jpit, this car has big brake package and 15 in. wheels, no clearance issues. The rear of the car is lowered as far as the spring stops will go, the front is lowered to approx. 3/4 of spring stop adjustment travel. The backspacing on the rear wheels was increased by a local machine shop. I added 10mm spacers to the front wheels to fill out the fenders more. Rear tires just barely rub the inner wheel well on the harshest of bumps. 295/50 rear, 245/60 front. If you go the 15 in wheel route, I would suggest having the backspacing custom machined to your specs, there is plenty of meat on the Trigo wheels for this.



I have no flex in the dash when turning the wheel. There is a brace that runs from the steering column bracket to the firewall, I would check the integrity of that.

Wolf k, your car looks great. The way your car sits on the tires looks perfect. I am going to call the guys up at ERA this week and confirm that I can get 15in wheels over the big brakes, a ball park price for the whole project, and if they can do it over the winter.

Thanks for everyone's help

John

I'm not saying that those tires will rub. Only that I can't guarantee that they won't. There are variations in the body, not to mention not all tires rated to be a certain profile will measure the same. I have to be pretty conservative when I make official "factory recommendations".
