beataru Posted April 8, 2008 Share Posted April 8, 2008 Ok so I was rotating my tires today, in my driveway, no time to do it at evit and after getting the right rear side tire off the ground, about 2.5 3 inches, I placed it on stands and went to the front, when I got the front up to the same height, I put a stand under it, and look at the rear... It was back on the ground.... So I said to my self "Self, this cars chassis is not very stiff at all, I wonder if any of the guys (and girls ) on usmb have seamwelded/fully caged one of these cars, so after searching a bit, I found only a handful of seamwelding posts, so it appears that not many of you plan on having these cars as your weekend racer ... but I was wondering if any of you have expierimented with seamwelding, either on these or on any car, and what were the results, if your really cool youll give me the weight added from the welding. The reason I am asking this is, before too long I should (hopefully) graduate highschool and have a full time job at either a dealership or mcdonalds or whoever gives me the best deal... anyways, I will be slowly fixing up my -10 to try and get it AutoX worthy. yes i know i can autocross it as is, but Im in it to actually not be last, maybe even top 5 . I will eventually have a car that will handle, and it will do so because I made the modifications to it. so wow After realizing I am writing a novel, Im out, tell me what you guys know about it.

merkatroid Posted April 8, 2008 Share Posted April 8, 2008 Seam welding takes alot of time and would require you to remove most of your interior to perform the welding. Also any sound deadening would come out at the same time. It does make a big differance on chasiss stiffness but unless your making a dedicated track car or a really bad rump roast turbo'ed impreza with a cage and ball bearing t67...probally not worth the hassle. That being said, the interior seams from the dash back probally wouldnt be that hard to do and would stiffen up the car alot. I can give you a hand preparing it and welding it if your serious. Im not sure a rollcage would be a good idea. Your Golden retriever would have to wear a helmet to ride in the back. Quote Link to comment Share on other sites More sharing options...
Quidam Posted April 8, 2008 Share Posted April 8, 2008 Hey, I have an eighty seven GL, 2 wd, 5 speed wagon. If I put a jack under the right rear tow hook, jack it up, the front will lift off the ground as well. If I remember correctly, there was three quarters inch difference between the front and rear tires, and the floor. That's not bad at all. Not sure about front to rear. If I drive my 4wd up a bank, sideways, kinda. Say right tire contact with the bank, the left front tire will be off the ground, and I'm sitting pretty level in the car. Not bad at all. The RX sedans that won the WRC championship were seam welded, with reinforcing plates. That would be even better, for sure. Just thoughts, Doug Quote Link to comment Share on other sites More sharing options...

On another note, the wrc cars used reinforcing plates? please do tell Quote Link to comment Share on other sites More sharing options...
Quidam Posted April 9, 2008 Share Posted April 9, 2008 On another note, the wrc cars used reinforcing plates? please do tell Hi, I've looked. I haven't found what I was looking for.

beataru Posted April 9, 2008 Author Share Posted April 9, 2008 So theoretically, if i could spell... There are much more simpler ways of stiffening up my chassis without seamwelding. Roxy could wear a helmet if I got a roll cage. It would be nice to have my very own RST stomper. Quote Link to comment Share on other sites More sharing options...

joostvdw Posted April 10, 2008 Share Posted April 10, 2008 It looks like the only thing they do is just slap on some extra sheetmetal? Can someone post a picture of a RX without the fender? I would like to see if I can see why they reinforced that specific part of the body. Quote Link to comment Share on other sites More sharing options...
beataru Posted April 11, 2008 Author Share Posted April 11, 2008 I imagine its going to be a bit stronger than sheet metal :-p Just kidding Quote Link to comment Share on other sites More sharing options...

carfreak85 Posted April 11, 2008 Share Posted April 11, 2008 Nissan used that stuff in the older Infiniti Q45 sedan. You can trust it in your wet noodle wagon chassis, I plan to. Quote Link to comment Share on other sites More sharing options...
beataru Posted April 12, 2008 Author Share Posted April 12, 2008 That stuff would be better than gutting my entire nearly perfect gl-10s interior. Quote Link to comment Share on other sites More sharing options...
