Assuming the ambient temp gets to the area you mention; your trunk gets hot enough that with prolonged exposure the composites are going to change their composition to some degree. I have baked enough composites to know, but don't trust me! Nike's Golf Product Development Manager Rock Ishii agrees.
Can you perceve a difference in your equipment? Now that's another story!
I agree with Fourputt on this one. Leaving your clubs in a car trunk will not harm them in any way. Like him, my clubs rarely leave the car and have been exposed to both cold an hot extremes. I have never had a clubhead fly off because the composites broke down. I have never had a grip feel dried out and useless. I change grips every year and have never had one be brittle and dry.
Furthermore, I have a few clubs that I have used for several years and even over time there has been nothing wrong. I've had my 3-wood in the bag for 15 years and it hits the same as it always has. My 2-iron is a Ping ISI and I have had that since new (10+ years?). My driver is 7-8 years old. I have had no problems with any these clubs and materials breaking down.
I live in an area where it is hot for 3 months, cold for 3 months and anywhere in the middle for the other 6. Maybe, and this is a big maybe, if you lived where it is 90º+ (or below freezing) 12 months a year and your car was left in the sun the whole time, something might happen to the clubs. I don't know of many places on the planet that are like that, and if you lived there, you probably wouldn't play golf anyway so it won't matter.
