I had the uniball kit fitted: definitely a less resilient ride over the bumps, but there is zero slop/deflection mid turn and the steering is ultra precise. For a track car, I think it's worth it.

The larger diameter (360mm) is what gives the biggest gain in braking force. The difference is between 'wow, awesome brakes' for a passenger... to 'OMG, I'm nauseous'. I was advised by Manthey that the MR designation was correct for my car.

The 2.5k price includes the 6pot calipers which a Mk2 owner will not need.

Adrien,

mailed you at the old EY address. Is this still correct ?

Nope, I left them 6 months ago! YHM.

Excellent points. I run the stock wing, but played with the shims alot during the Sept/Oct months. Your findings match my own. I run the 8 in the rain, and the 4 the rest of the time. When someone gets pushy with me on the straights, I swap the shims out and get an extra 5-10 mph.

I have been running the 4 degree shims with the RS CF wing but will be moving to the 8 degree shims to get that little extra downforce that is coveted. I'm willing to give up a mph or two on the straights to get better grip in the high speed uphill esses and approaching the braking zone at T1 (VIR).

Smart move Dell. When I run full track at MMP with the .8 mile main straight, it is good to get that extra speed. Taking 20mph off the top end with the 8 degree compromises too much. It really depends on the track.

Hope all is well with you and your family in NC.

Considering MMP is freakishly long and little elevation change I'd probably run the 4 degree shims or maybe even none. Our back straight at VIR though is 3/4 mile but UPHILL at the second half where the crappy gearing in the GT3 struggles Every once in a while if I nail Oak Tree I can cross the 155 mark but for the most part I'm in the low 150's.

Family is well! Great Christmas with the new little one

ps. why does it say on the MMP website that the front straight is only 3500ft? That's only 2/3 of a mile.

blake

You got me Dell. For two years I have been telling everyone MMP is .8 miles on the front straight, and it is only .67 miles. I stand corrected.

I will say that the staight is so long and wide that one could probably finish a tall Starbuck's coffee before reaching the next turn....

So do you think you will ever make it out to MMP in 2008?

NOw it sounds more reasonably. 1,4 k withe 3-4 times longer.
Adrien do you think that difference between 350 and 360 has so big impact on braking performance. And Alcons are floated disc?

What pads do you use to alcons? Im thinking about PFC 01/097.

LVDell

I'd love to but damn this is a long tow!

I have no empirical evidence for the increase in brake force leverage, but I'm guessing it will be some factor of the increase squared. The Alcons are a floating disc, and they are spring mounted which makes them silent in operation. (unlike the comparable Brembo floating discs which rattle like your gearbox is going to drop on the floor! )

I've been using RS29s which have been superb once up to temp. My current Alcons have lasted me about 20 trackdays spread over the course of about 20k road miles yet appear only about 1/3 worn. They still operate silently and I have not noticed any extra movement/wear across the bells. I am only on my second set of RS29s over that same distance... but I think that is as much a factor of me learning to brake lighter and lighter as I've tried hard to improve my braking technique.

I've also swapped to Alcons, 6 pots and RS 29s. Confirm Ade's comments that after a "season" there is hardly any wear on the discs and the braking power & feel is immense. I was mucking around at Spa earlier this year and found that at the end of the Kemmel straight (over 150 mph) I could brake well within 100m and still get round (in a fashion!).

But this wing business has got me thinking - Damn that Adrian guy

The other great test: end of the Parabola at Hockenheim into the hairpin... down from 160 to a 1st/2nd gear 180 degree hairpin... Even after a whole day lapping there in mid 20deg C weather, the Alcons were rock solid with zero fade.

Always happy to help those afflicted down that slope!

The Mk1 needed more rear downforce... hence change on the Mk1 Cup car to Big Wing spec in 2000... once you make the change Ric, you will never look back!

Be gone u orrible man!
