rfcbuf Posted September 5, 2005 Share Posted September 5, 2005 I am hearing that the roof rack on suv's ( I have a 2004 RX 330) can increase gas consumption. I have 3 questions: 1. Is it true that removining the cross members on my roof rack will improve gas mileage? 2. How do you remove the roof rack cross members on a 2004 RX 330? 3. Will removing the cross members weaken the roof rack assembly? Quote Link to comment Share on other sites More sharing options...

katzjamr Posted September 5, 2005 Share Posted September 5, 2005 This was a topic in the rx330 forum a while back. I did a search under 'roofrack removal' and a few posters describe how they removed the rack. They were concerned mostly about wind noise.

bartkat Posted September 6, 2005 Share Posted September 6, 2005 really how much does it way?? ← If you mean "weigh", that all depends on how much stuff you put on the rack, but removing it is not about weight. Quote Link to comment Share on other sites More sharing options...

Do a search as someone has already mentioned, I remember it sounded simple. 3. If the Lexus factory rack functions anything like a Thule (for which only I have experience with), removing the cross bar makes the rack completely useless because you need to install attachments on the crossbar to properly secure whatever you're carrying (skiis, bikes, surfboard, etc.) Quote Link to comment Share on other sites More sharing options...

Conservation of energy, energy spent to generate noise you heard from roof rack can be saved or used to propell car forward. We don't ever see non-wagon/SUV (e.g. sport coupes) have roof rack as a standard feature. Quote Link to comment Share on other sites More sharing options...
dmcquade Posted September 8, 2005 Share Posted September 8, 2005 I checked into this a while back. I found one site that claimed a 1% - 2% MPG improvement by removing the roof rack. I ended up leaving them in place as I do mostly city driving and the savings was minimal. If you fill up every week at a cost of $45 a week, you're spending about $2160 a year on fuel. With a 1% - 2% deduction you're only saving about $21 - $42 per year by removing the rack. My wife and I started started riding together 3 days a week (17 miles each way) and that will add up to $530 per year in savings. My take on the whole thing is that if you're looking so save money or the environment, cut back on your driving and make sure those tires are properly inflated. Just my humble opinion. :D DJ Quote Link to comment Share on other sites More sharing options...

I have seen a 99 RX300 with black paint peeling off and showing the aluminum underneath. Black is fine, silver is even better looking, but spotted silver on black is a wore looking roof rack. If you have a stone cut on your RX330 roof rack, you can verify whether it has same paint as RX300's. Quote Link to comment Share on other sites More sharing options...
chimchim Posted September 9, 2005 Share Posted September 9, 2005 We never use the roof rack. So how do you remove the crossbars? I'll just put them on on those rare trips that we actually do use the rack. (haven't yet) Quote Link to comment Share on other sites More sharing options...
