im buying some leader gears. a new run is about 2 occur within 2 weeks. is anyone serious about purchasing these gears. if we get a few ppl we can get a discount. Street 2 Strip is doing me a sweet deal AUD$1,140.00 delivered by air withing a week or you can be a stinge and pay 1040 delivered but takes 10 to 12 weeks. any other questions plz direct them 2 Paul from STS any one doubting them may want 2 consider this from there sight "There are a couple of considerations you must be aware of before you purchase these gears. 1. Your car will be faster. And without adequate traction you will not be able to put the power to the ground. " http://www.leadergears.com/site/content.php?content.5 yes i realise that its almost xmas and some ppl may be strapped 4 cash.. im just putting it out there. im buying them with a gb or without
I may be interested in these once I sell my house, predict february-march. What rpm would we be doing with these in at 100km/hr in 5th gear? I presume that these reduce top speed as a payoff for increasing accellaration. What is our top speed reduced to? And any ideas on installation costs?
by my calculations. and for my car. TT manual 255/45/18's with the 4.10 gears 7000 rpm in first - 68kph 7000 rpm in 2nd - 114kph 7000 rpm in 3rd - 169 kph 7000 rpm in 4th - 220 kph 7000 rpm in 5th - 294 kph 7300 rpm in 5th 307 kph more than enough to lose your licence EDIT . By the same calculations 100kph in 5th would be 2340 rpm 110kph would be 2570rpm These figures are for real speed too, not what your speedo indicates
My figures don't jell with yours .... car is a manual TT. Firstly at 100kmh in 5th with the stock 3.69 TT ratio, my tacho reads 2500rpm. Therefore I would expect switching in the 4.10 gears should increase the revs to approx 2780rpm at 100kmh. My car has been GPS checked and the speedo is within 1 kmh at 80kmh, and the quarter mile trap speeds of 107mph fairly accurately reflect the 170kmh showing on the speedo. Also, By extrapolating the same data in 5th gear, I would expect my Z to be reaching 280kmh at 7000rpm and 292 at 7300rpm. Installing the Leader gears should see those speeds fall to 252 and 262 respectively. Not many circuits around Oz where this would be an issue for me.
my rolling diameter is significantly larger than stock by my calculations the diameter of the stock 245/45/16 is 626.9mm my 245/45/18 is 677.7 I am working from a 0.75 fifth gear ratio which i think is correct
Aaah OK then, your tyres are significantly bigger. Stock J-spec 225-50x16 rolling diameter = 632mm. My 255-40x17 = 636mm. Yours - 677mm, 41mm or 6.45% more. Doesn't explain the whole difference but goes a long way towards it.
larger diameter wheels is effectively a gear in itself by using them, you have on your car something that creates the opposite effect of the leader gears in other words, if someone had smaller diameter wheels with the leader gears, then the effect would be enhanced... your top speed would be lower but you'd accelerate faster alternatively, if you change the gearing in your box you'd get the same effect (more expensive tho, but if u were doing a rebuild then something to consider)
PLZ stay on topic this is not a discussion about top speed. if you need more info there are tons of THREADS.. use search EOI on buying these gears . these runs are limited. and once there gone who knows when the next batch will be out
paul from STS has just informed me that if we can get 3 buyers price will be AUD $ 1,070.00 delivered via air frieght... the US guys are allready placing cash money orders so if anyone is serious now is the time 2 speak up THIS IS A LIMITED RUN!
These gears are awesome! Mark Leader and Paul (STS) generously supplied some for the DriftZ. They have been fitted with a full spool (fully locked)and have performed faultlessly!. The absolute hammering they cop in that car is testament to the quality of these gears.
How long can you wait? I'd be down for this say mid Jan. How long were you going to keep this open for? Or how much of a rush are you in?
