gripper differentials - Saxperience

AlexB^p · 17th March 2011, 13:01

Well i got mine today and oh my word what a piece of artwork from an engineers point of view!!

Ill do a little review after its fitted as ill be driving 185bhp on standard diff
Shame i cannot compare to a quaife but if anyone wishes to lend me one haha!!

So far im massively impressed just in the quality of it

raunchz · 17th March 2011, 17:42

What sort of preload and ramp angles you go for?

AlexB^p · 17th March 2011, 17:55

John set it all up but he done it quite light to suit mainly back road use so i dunno atm im gonna double check tomorrow afternoon and confirm them all incase i need to reset it ever

Basically its all on the least aggressive without slipping its still higher than a quaife lol

raunchz · 17th March 2011, 18:01

Should be awesome!!!

I've read reviews on these and they sound superb! If I was going for a diff I'd go for one of these!

Jay_ · 17th March 2011, 18:04

i think we need an "out of the plastic wrapping" picture....it does look lush though! sounds like a bit of a beast!

AlexB^p · 17th March 2011, 18:16

Jay i have one now aswell as one of the shaft with the 14 tooth final drive on lmao ill put them up in a bit

Barry123 · 17th March 2011, 18:28

well I know fuck all about grippers... so if anyone can enlighten me then please do

All I can say about the quaife is I didn't like it when I drove Yates' on the road, it would torque steer quite aggressively. Not strongly, just quickly, which was a bit unsettling. Presumably grippers are even stronger, judging by the name? I can't think of anything more terrifying in a saxo with 185 hp on a potholed country road, with alex driving it

Barry123 · 17th March 2011, 18:29

...oh and how much did it cost you alex?

AlexB^p · 17th March 2011, 18:38

roads by me arent that potholed ads but yea itll be a bit of an experience the first few times (im pretty sure ill pansy out a bit at first with the power)

they do torque steer a bit more yes but they dont loose traction which with 140odd ft/lb i think i might be struggling a bit on road tyres if im spirited its not gotta spin both up not just one like

and i payed (with discount as my dad used to race motocross with dave mac) 1020
they should be around 1200 quid
come with a final drive (of which you have a choice) and they look to be extreeeemely well built

Barry123 · 17th March 2011, 18:46

You get to choose your final drive? That's awesome - what have you gone for?
That price is an eye waterer. Your car is going to bloody amazing though.

raunchz · 17th March 2011, 18:47

I've heard you do need to grip the wheel when driving at a fast pace on normal roads.

But they are definitely worth it, the way you can accelerate round corners verges on being silly! Will all depend on how aggressively it's setup.

Should be awesome with the TBd engine and a nice twisty track!

yep custom straight cut ones so they whine a little haha
ive gone for 14/60 (1400 xsi) they do anything even custom longer ones for boost or silly short down to about 17/54 i think it was the smallest he could get on the diff)
price i think is worth it as the cars going to get a lot of summer use on sticky rubber (just got some cyclones to wrap in some) and ring trips ect aswell as track time i basically wanted it unbreakable

my stuff is all aimed at twisties the lanes by me ive had spinning in 3rd at about 85mph on my gti box as it came up the power so i deffo needed more in the diff so this should help a LOT!

as said mines quite mild but if i decide to go higher then i just need to get adjust it maybe get the harder springs (theres 2 or 4 different sets i have 50ft/lbs ones) so on its softest will be my little write up but i think i may get another with 120ft/lbs when i get my 205 built for the hills as they bite in a lot harder and launch better

Its a plate diff as far as I'm aware. Much better than the quaife as the diff works even if one wheel is off the ground. Should be fun!

sexy_gt · 17th March 2011, 19:49

i am poor and run a quaife. ive seen wheelspin at 70 with it. not sure if it was one wheel, im sure it was.

also 1st time driving in the wet i almost kerbed it. did not expect it to drag me across the road when the wheels lit up

enjoy your new bit

Dave_P · 17th March 2011, 20:22

Remember to keep a good hold of the steering wheel when driving.

My 106 has a Gripper LSD, the Saxo will be getting a Quaife.

titchster · 17th March 2011, 20:38

Keep away from them bastard kerbs!

Nice purchase though fella.

I plan to keep off kerbs on the road
On track maybe a little rumble isnt a bad thing lol!!

BETTER ??
that all down to type of usage --would not be my choice for a road car/ occasional track day car --a bit to aggresive +expensive for most people .
the big advantage if you are making a real track car and do not mind stripping and readjusting the plate tension every now and then, is the choice of final drive ratios available--but at a price
but that in itself doesn,t make the gap in the ratios in the box any better --
for full track car add a c/r gear kit to it as well, and gear it so max bhp rpm =around 120mph for n/a car at most--then you will never feel its labouring to keep it on the "boil"

for a rally car make max bhp rpm =100mph

lowering your gearing by 40% will give you the effect of 40% more bhp at wheels .as far as acceleration is concerned--so fitting the right gear ratios --will be just as effective as spending alot on getting more bhp ,in lap times (well not quite ) ,but its the first thing you should spend money on
yes you can have wheelspin at any speed --it will be both wheels at 70 mph + wet roads.
the quiafe will only unlock when one wheel is lifted if you back of the throttle ,so if its kerbs on a race track ==keep it under power and it will not unlock --just fly across them

AlexB^p · 18th March 2011, 10:26

Its only to agressive if you set it that way though

axsaxoman · 18th March 2011, 11:57

If it does not have more locking than a quiafe --then no point in fitting it. and more locking means more torque steer etc,
the turbo ford focus have quiafes fitted as std --not plate type .
I have used 3 different makes of plate difs ZF ,,gripper ,citreon sport ,over the years in ax/106/saxo and 2 types of gear type difs ap suretrack +the quiafe so i have had experience with both types of unit
I am not saying gripper is not a good make ,but I maintain it is not the best all round chioce for a road /occasional trak day car ,thats all

I would certainly suggest you increase castor angle to around 4-5degrees when using a wound up plate dif .
and if going to the cost of this unit go for the BE size splines in the dif+ same at drive flange endin the the hubs as well ,which then means new shafts of course--more grip/snatch is more strain on the rest of the transmission
