you are a true pioneer<p>Just an idea: talk to George, not necessarily to buy from him, he could give you ideas ideas on parts and fitment<p><A HREF="http://www.vivaperformance.com/catalog/product_info.php?cPath=81_113&products_id=665" TARGET="_blank">http://www.vivaperformance.com...d=665</A><p><IMG SRC="http://www.vivaperformance.com/catalog/images/QDF13J.jpg" BORDER="0">

Re: quaife qdf14j...front lsd for the R (FEO)

This might be a dumb question, but why are all of the performance differentials only for manual transmissions? why do they not make one that will work with the GT?

Re: quaife qdf14j...front lsd for the R (GGV70R)

Hey, this is an odd post, but...who's the guy who was interested in this diff?<p>Sorry man, totally forgot ur username....I think it was something like Jon...or Jeremy... with some numbers at the end.<p>Anyway, I'll be placing my order at the end of the week, so if you still interested, pm me.<p>BTW, if some of you guys/gals are interested in buying a front diff. for the m66, please chime in...could possibly get a gb discount:<p>Regular price: £645.00 GBP + Freight + VAT....+customs fees<br>Here's the discount quotes I got:<br>5 Units – 5%<p>6-9 units - 10%<p>10-14 units - 15%<p>15-19 units - 20%<p>20-25 units – 22.5%<p><br><BR><BR>

Re: (ClemsonS60R)

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD><i>Quote, originally posted by <b>ClemsonS60R</b> »</i></TD></TR><TR><TD CLASS="quote">what benefit is this on the R with our haldex AWD..?</TD></TR></TABLE><br>The R has 3 diffs:<br>haldex is the center diff.; it's basically like a clutch for the back wheels, and when needed, it engages and some of the power is sent to the back (I think up to 50%). This is actually the reason why the angle gear splines fail, when the haldex clutch locks, it creates a shock load on the splines which after a while strip. <p>The Front and Rear diff. is the ones control the torque split between left and right wheels. Volvo uses open diffs for front and back, which actually sends power to the wheel with least traction....so if the left wheels are on pavement and the right ones on ice, all of the power will be sent to the wheels on ice(although traction control will actually apply the brakes on the spinning wheels, to send the power to the other side). It also causes torque steer because of uneven drive shaft lengths of the front wheels.<p>With LSD, the torque split is evened out between the left and the right side and if one wheel starts to slip, the power is automatically biased to the opposite wheel with more traction(basically complete opposite of an open diff).<p>Hope that makes sense, if not, there's tons of info on the net about LSD's.<p>Benefits:<br>For me , the most attractive benefits of installing a front LSD is that I could make a switch to turn off the haldex unit and run in FWD mode most of the time without having torque steer, and possibly better acceleration times. This should also improve fuel economy(if running in fwd), extend the life of my splines/sleeve, the haldex clutches, and the rear diff. (since haldex unit won't be active), and should keep the traction control from constantly stepping in(which in theory should also extend the life of the brake-pads). <p>Then, when the extra traction is needed(like rain/snow/mud), I could just hit a switch and have AWD again. <br>
