T.C.,
I just wanted to point out that I believe the kit strengthen this part. You see the place where the jack goes so you now should know where this is. Sorry to make every one guess where it was in the car. I am more intimate with every part of my car as I am so close to it. Now that I have 1/3 of my GT kit in my welding is getting much better. This will mean less grinding for me. Bob (IMG:style_emoticons/default/welder.gif) |

I just wanted to point out that I believe the kit strengthen this part. I don't think so. This part is a double-wall and the GT piece is on the other side of that double-wall. There's 1/4" of air between the spot-welds inside the trunk and the GT "reinforcement" on the other side. What people don't realize, the GT chassis kit was a complete shot in the dark by Porsche. They added a few patches where they thought they might add some strength. They were under tremendous time pressure to get those cars ready for the track, this wasn't a well thought out and engineered product. I'm sure there's quite a few people today who could come up with better solutions ... (IMG:style_emoticons/default/stirthepot.gif) Andy |

(IMG:style_emoticons/default/stirthepot.gif) Andy ...I agree with SirAndy...I have been researching the web and looking through historical books for placement and attachment of the stiffening plates. This is what I have found. CONUS - most of the people that have added their stiffening plates have actually applied them to the outside vertical wall of the boxed section only and have not carried the additional metal over the seam. This is focusing more stress to the spot welds along the seam. The 90 degree sections just above the seam would act like "live" hinges under extreme stress. The stiffening plates end at least 6 to 9 inches forward of the trans-axle cross member. I would seam weld all that is shown in your picture on both sides. Europe - Porsche welders were not known to produce beautiful welds. Most of them were pretty uguly in fact. But note the wrapping of the metal over the seam in the attached photos. This wrap ties the two 90 degree bends with the seam and is much more stronger than just laminating the vertical wall. Dave |
