but man i gotta do some research about all these female members here. i think i'll put a little ad up in the non-car related section.![[hihi]](/images/smilies/icon_smile_hihi.gif "Hi Hi [hihi]"){kind=icon}
speaking of abusing your car... i was 'flexing my cars muscles' and i accidentaly pulled my steptronic shifter into 2nd going 65 mph or so. the tach bounced off 6200 and came to 5800 rpm or so. i quickly went back to 3rd and proceeded to 5th. i decided maybe tonight wasnt such a good night to give my car a workout anyways. i dont think i did any damage or anything, but i certainly dont like to drive my car very hard. as long as you maintain your car (change oil regularly, check tire pressure, etc.) there really shouldnt be any negative effects to letting your car free on occasion, right?
ya, bmw 325i is right. there's no way your computer would let you get away with that. furthermore, if you were driving a manual transmission and tried to shove it into second gear at 65 miles per hour, your sychros wouldn't allow it. it would make bad noises though. when i was still a stick n00b, i frequently put the car into 3rd from 4th. but i wasn't going any faster than 60, and 3rd handle's 60 like a pro. thank god for synchros though.
Re: Gearing
Sorry for digging up an old post but.... I am assuming that BMW changed the gearing over the years right? Because my 2nd gear is good till 71 @ redline (6600)![[thumb]](/images/smilies/icon_smile_thumb.gif "Thumbs Up [thumb]")
Oh the 2000 rpm drop gives me the proper amount of wheel spin prior to hookup. It does seem kinda low though I'll try it out again soon and let you know might be 2500.

Re: Re: Gearing
ya, not only have they obvioulsy changed gear ratios, but i believe they have also increased the redline. mine is 6500 RPM and second gear really won't let you go much over 50. newer cars are obviously designed "better" and can handle higher speeds in lower gears at lower RPMs, for instance.

On a manual car, it's different. It will let you shift down if you want it to. Synchronizers aren't controlled electronically at all and its only function is to creat friction between the collar and the gear so that the dog teeth of the gear can be engaged smoothly to the collar. If your hear grinding when you're downshifting, it's probably because your synchros for the collar that matches that particular gear is going bad, causing the dog teeth on the gear to not match up correctly with the collar.
I've never downshifted passed redline, but I knew a guy (who is a complete idiot) that did downshift passed redline on his E36, blowing his motor- so that's proof it's possible.
Your E30 M3 looks very clean btw

, i'm embarrased to own the same brand of car as he. also, i wish that were my E30 M3 in my sig. however, if you click that picture you'll see a pic of my engine-the M20 of my 325i.
