How bout that...close but no cigar! Anyone else? Here’s my setup.

I have a Borla EFI 8 stack setup with 50mm(short) air horns. Anyone with clearance problems with the tall stacks(75mm) that would like to trade for short ones? I’m in LA, CA.

New developement...I received the new o ring and cleaned the old one to compare. After cleaning and closer inspection, I found that what I thought was dried silicone on the old seal was actually some slices on the outside of the O ring. On comparing the 2 O rings, the older one is larger in...

Apparently, Powerhaus is no longer in business. The phone number connects with a business that deals in Porsche but they are not open over the weekend. Anyone else that can give me guidance, it sure would be helpful. I’m curious as to why there was some silicone sealer on the O-ring and whether...

Thanks Howard, that may be the way to go. I should’ve thought of that yesterday. I have the O-ring and would like to button this up over the weekend… I’ll give them a ring and see if they’re in the shop today.

I can't speak to the Hoosers but my Avons don't flat spot. I think the old style Goodyear Billboards have that issue, but once they warm up a bit they round out. I don't believe you'll need to store on stands unless youre looking at prolonged storage. At $550, I'd grab them...especially if...

I run Avon racing tires on the street, mostly to weekend cars and coffee events that are close by. I couldn't find suitable width and profile for my 15" diameter rims in a DOT approved tire. I drive very conservatively, constantly watch for road debris as they are more suseptable to puncture and...

Hello! A question for those with 930 transaxle experience. I purchased a new G50/52 transaxle that had been modified for inverted use.(Powerhouse) After the modification it sat for 10 years before I purchased it and installed and ran it. As soon as I put oil in it and drove it a bit it...

This is a timely thread as I had planned to post regarding this to find out tricks or tips to making the RCR hand brake system function better. With much fiddling and some modifications, the best I can get out of the system is a snug drag...enough to where I can’t push the car by myself but not...

Thanks Howard! It’s been a week or so since I did my first testing and now that I remember, I did torque down one of the other old adapters to this assembly and it was within spec. So it would seem I was sent a defective replacement adapter. Kim

OK, I found the culprit. Never assume "New" means good. Here is what I found after "blueing" the back face of the new adapter and sanding it with 600 grit sandpaper on a super flat surface. As you can see from the photo there is a low spot around 25% of the outside of the adapter. I checked...

Hey Randy, Yes I checked tthe run-out of the hub and it is within tolerance as well. I’m going to “blue” the bottom of the new adapter and scrub it on a flat surface with a piece of emery cloth taped to it and see if there are any high or low spots on the back face of the new adapter.

Thanks Keith, all the drive pins are torqued equally. I will re-check the bolts that connect the rotor to the hat. All surfaces are clean and straight to the touch and eye. I have also torqued the rotor hat down to the hub without the steel Spacer plate and the results are the same as with the...

Thanks Doc, I’ve rotated the hub to adapter 2 bolt holes which amounts to approximately 130° (because of the five bolt pattern) and reinstalled and have the same results. I’ll try rotating the adapter just one bolt hole and try that. Not hopeful however.

Whenever I find myself scratching my head, I go to this forum and the incredible wealth of info that you all share so graciously never fails to enlighten. I've been doing some fine tuning on my RCR GT40 and have come across an issue with brake rotor run-out. The last time I drove the car I had...

I just completed my RCR GT40 build. I have 3 years and over 2600 hours invested. I did all the work myself with the exception of spraying the final color and gloss coats. I was very driven and devoted a lot of time to the build. There was a point in the build that I had to walk away for a few...

The half doors were sold as such, modified by RCR for more of a T top look. They were made and sold about 10 years ago and have never been used. I’m not sure if they offer them anymore. Kim

PM me with an address of where to send it and I’ll get an estimate of how much it will cost to ship. Kim

I have hinges that were take-offs from a New Superformance. I bought them thinking I would hinge my nostril but decided not to. Let me know if you're interested.
