Bob_260 Posted May 16, 2016 Share Posted May 16, 2016 First of all I want to apologize to the group, I'm sure this question has been covered before, but after searching for a couple of hours I haven't had any luck finding the right postings! So I'd appreciate people pointing me in the right direction. I have a 10/73 build 260z with coilovers and I'm running 235/45/17 tires on 17x8.5" Rota rims. No flares, just rolled the fender lip. I'm getting ready to paint the car this summer and I'm considering fitting the Xenon Ducted Urethane Air Dam before painting, but I'm concerned about clearance when the tires are turned to the limits. Originally I had to trim about 3/4" off the lower valence sheet metal to gain enough clearance to eliminate the rubbing. My question is: am I going to have clearance problems with the Xenon Air Dam and if so how much can I trim the Xenon Air Dam without butchering it? Thank for your help and your patience with my search skills! Quote Link to comment Share on other sites More sharing options...
Leon Posted May 16, 2016 Share Posted May 16, 2016 The Type 1 Xenon air dam angles away from the wheels. While I can't guarantee that you won't have issues, it's definitely got more clearance than the stock valence. Quote Link to comment Share on other sites More sharing options...
Bob_260 Posted May 16, 2016 Author Share Posted May 16, 2016 Thanks! For the quick response. If I do have a clearance issue, do you know if the Urethane Air Dam can be trimmed or is it "game over'? Quote Link to comment Share on other sites More sharing options...
Leon Posted May 16, 2016 Share Posted May 16, 2016 I don't see why you couldn't. Quote Link to comment Share on other sites More sharing options...
scott Posted May 16, 2016 Share Posted May 16, 2016 I have that air dam on my 73 and I used a large metal file and easily removed material. I was also able to bevel the edge of air dam inward for more clearance. The file was easy to control the amount taken off. I did this with tires mounted and car sitting on ground and the air dam was already painted...no problem Quote Link to comment Share on other sites More sharing options...
zlalomz Posted May 16, 2016 Share Posted May 16, 2016 I trimmed my xenon air dam to clear some 9 inch autocross slicks years ago. Quote Link to comment Share on other sites More sharing options...
Bob_260 Posted May 17, 2016 Author Share Posted May 17, 2016 I was concerned that the back edge was just a thin lip of plastic, which once I cut it off the sides would not be supported (I haven't had the chance to examine one of these air dams in person) but from what you guys have described it sounds more like it's fairly thick lip which can be trimmed (filed down) within reason. It also sounds like the line design may give more room than the factory sheet metal. I think I'll go ahead and order one and fit it up. Worst case I have to sell it and someone else on the forum gets a bargain! I'll try and follow-up on this post as I progress. Thanks for your help!

Bob_260 Posted May 27, 2016 Author Share Posted May 27, 2016 Hey! I want to give you guys an update. Just did the first trial fitting of the Xenon air dam tonight and it clears the tires (235/45/17) with about a 1/4" to spare on hard turns. I may tweek it a bit with a file or a sander as suggested. But so far I have had any rubbing issues, straight out of the box! I've attached a couple of photos. Thanks for your help. I hope this tread can be of assistance to someone else in the future. (Assuming their search skills are better than mine and they can find it Quote Link to comment Share on other sites More sharing options...
240zdan Posted May 27, 2016 Share Posted May 27, 2016 (edited) Do you plan on tweaking your caster with adjustable TC rods rods? Mine at 5 degrees rubs slightly, but I live with it as the stability feels amazing. Something to keep in mind.

Bob_260 Posted May 28, 2016 Author Share Posted May 28, 2016 Good point 240zDan". I did installed adjustable TC rods when I did the Coilovers upgrades & big brake upgrade about a year ago. I don't remember where we set the caster angle when we did the final alignment. I'll have to go back through my records. Quote Link to comment Share on other sites More sharing options...
240zdan Posted May 28, 2016 Share Posted May 28, 2016 (edited) Im going to guess its at 5 degrees Edited May 28, 2016 by 240zdan Quote Link to comment Share on other sites More sharing options...
