I agree. It was so annoying that I sold my Black M7 and ordered an NRB A6. really pleased with it and use the paddle shift frequently.

I either own or have owned every generation Corvette expect a C1 or 2 and it is remarkable how incredibly easy it is to drive the M7 C7. It's almost too easy ie: the brake assist on hills until the clutch engages.

And I agree about the inferiority about the old stuff. They're fun to look at but not so much fun to drive after you've driven modern technology.

Yep, some cling to the myth that it can't be a heavy-duty, high performance, manual transmission unless the clutch action is ultra-stiff and it grabs as soon as it leaves the floor. That's just not true anymore. It isn't desirable either, unless it it makes you feel better to replicate the past.

If anyone had 650 ft/lbs. of torque in the old school stuff, they were changing clutches pretty often.

This is my first manual car and I learned on it. Clutch annoys me sometimes and I find it much easier if I let it out half way while anticipating the light to change so I don't have to go that entire distance to bite point.

I drove a friends Challenger Scat Pack and that clutch felt just right to me, felt impossible to stall with where it engaged and how wide of an engagement point it had.

Foosh: It's not about old school vs. new school. (I have never driven an old muscle car in my life.) It's about the C7 clutch relative to other clutches, old or new. On the C7, the throw is very long and it engages very high. Many, myself included, find it annoying.

Tilton may have an adjustable master cylinder that would give you what you are looking for. I put one into one of my cars and it changed the pedal bite point quite a bit.

It seems to be more about perceptions, preference, and technique. I find the clutch perfect as is. Halfway is the perfect engagement point, unless, I suppose, one has a very slow left leg, or physical problem.

It may be perception...but I would love to have halfway. Mine is nowhere near halfway.

I'd recommend that you evaluate the full pedal travel again. I bet it's close. If it really is very near the top of travel (after you've released the pedal), you may actually have a problem.

I did that very thing this morning to verify my perceptions, and the engagement point is pretty much dead-on the halfway point.

Its just about 3/4 exactly. I spent a lot of time with it. It was the one thing about the car that was not second nature to me. I guess its possible that there is a variance and your car is different. There are enough threads and enough people with this issue that its not imagined.

I didn't say it was imagined. I do think a lot of people think halfway is too high. Many also disagree with that, myself included.

I suppose there could be variance between units, and also think many are exaggerating.

I have an 04 GTO with an aftermarket clutch. It grabs right at the top, and is so heavy I'll probably be having hip replacement sooner than later, but you can shift it very fast. All you gotta do is give the clutch a smack with your foot and it's enough to get the car into another gear. Then I get in the Corvette and about put my foot through the floor board till I get use to it. I like the Corvette clutch. It's just right.

Sitting at my computer, I honestly have no idea the level my clutch engages, it is just so automatic that I don't think about it. I got used to it after about 2 miles from Kerbecks.

I find the clutch the C7 extremely easy to use.

My 2014 clutch has been perfect (for me, anyway) since day #1. I wouldn't change a thing about it.

Less "feathering" required on this car than any other I've driven, although that's not saying much since the only other manuals I've driven have been other Vettes and Camaros. I like the clutch the way it is and after 25K miles, it's just second nature to me now.

I have driven four Mustang GT coupes (all with five-speed manual transmissions) and the clutch on my 2017 seems head and shoulders above them - as it should. Sometimes it almost feels to "easy" for such a high-performance car......but it is hydraulic instead of "dry" - so that's natural.


I have driven "old school" manual transmissions before and the C7 is light years ahead - as to be expected. I am just curious as to how long the clutch will last if driven with a modicum of sanity. My last stick-shift car was a 2002 Nissan Sentra and I still had the OEM clutch, pressure plate & throwout bearing at 162,000 miles when I sold it.

I don't have a lot of miles on my C7 yet. Also have a RX7 I've owned for 20 years. I hadn't driven the RX7 since I got the C7 and last weekend pulled it out for pics to sell it. As soon as I started to let out the clutch I realized that was something the C7 was missing. It engages nearer the floor and the feel is much better. I'm sure I'll become more used to the C7, but I know I'm giving up a really great driver.

I prefer the C7 mid-way clutch engagement point compared to other manuals I've driven with engagement closer to the floor. I find it easier to drive more smoothly.

However, every manual is just a little bit different, so it's just a matter of getting used to whatever you're driving.

^^

Don't see what all the concern is about the need to catch lower? Makes it easier when going through the gears not to have to engage lower. When the trans fluid is cold, I do depress the clutch fully when going into 2nd (not sure it's needed but do whatever to make that "stiffer" shift best possible.)

Once the trans is warm don't depress the clutch fully even for the 1st to 2nd shift. No grinding cold or warm I just use more force when cold.

Firm pressure to the left on the 1-2 makes that issue largely go away.
