I know that some people say that having a sun roof reduces the chassis rigidity due to a whole in the roof, but is this the case with EVO's? Any reduction in handling?

 

Yes. Plus the added weight up high.

unless your a serious racer its nothing to worry about..

My sunroof hasn't kept me from passing quite a few full on race cars as well as some very serious street machinery on track days. I'm a 6' tall driver and the sunroof clears my helmet just fine.

 

sunroof open...your aero totally suffers...but like what ppl say, unless you're a serious racer, or you're going like 600 mph... it's very insignificant.

 

duh, evo sans sunroof always faster than evo with sunroof.

 

my friend has an evo with sunroof and I have an Evo without sunroof and I beat him by 10 seconds at the last autocross

 

Driver, not sun roof.

 

duh, should have I added the sarcasm tags for you?

 

Apparently

 

the sunroof effects are very minimal...i don't notice the difference.

 

Nobody ever lost a race in an Evo and then cursed the sunroof. The positives of having it open on a day like today far outweigh getting from point A to point B .000whatever seconds slower.

 

His question wasn't "How significant is the reduction in handling?", his question was "is there a reduction in rigidity/handling?". The answer is simply "yes". If you want a different answer, ask a different question.

BTW, there is an interesting Mitsu design doc out on the web somewhere about the design and rationale of the aluminum roof, which is a heck of a lot less weight difference than adding a sunroof. Interesting reading.

agreed

 

sunroofs suck.i still can't get over the fact that they made them on the evo
