I had to remove a wheel the other day and I realized how damn heavy they are! Reducing rotational mass is huge for all around performance so it might be time to lighten up.
I currently have Hartmann RS4 reps and I really don’t how much they weigh, thinking high 20’s.
Enkei and Oz have some lightweight alternatives as well as Advan. (I think) What are some others? I haven’t seen this discussed on AR… I did search.
Really depends on how much you want to end up paying. You can get some pretty light 19s, but is the price tag worth the performance, probably not IMHO. I would say OZ ultraleggeras in a 19" are your best bang for the buck.
Enkei RP-F1’s hands down. Mine weighed in at 42lbs each with 245-35-19 general exclaim tires. (which sucked BTW>)
I’ve had my eye on these http://www.tsw.com/alloy_wheels_Nurburgring.php and these http://www.tsw.com/alloy_wheels_Interlagos.php
Without getting into crazy expensive Volk’s, Enkei RPF-1,s would be the lightest. My 18’s weigh 41 with tires
For reference, stock wheels weight about 27lbs each. Most tires are between 22 and 25lbs for 19’s
I would say that lots of tires weigh more than that Joe…normal for nineteens would be around 24-26 with some being high twenties
Typo. Meant 18’s
Buying rs4 tires sucks…they’re all extortionate and heavy as fuck
Thanks guys, the Enkei’s are at the top of my list due to weight/price. The B7 certainly isn’t a track star but shaving off an est 8-9lbs per wheel is substantial.
I was told or read the unsprung weight reduction has a 6:1 ratio to curb weight. Can anyone confirm this and does this figure differ based on AWD or 2wd? In other words, losing 8lbs on each corner equates to losing 192lbs of curb weight.
I felt a big difference when I droppe the weight. However, I did JHM LW front rotors atthe same time. I actually just switched to stock rotors again and honestly I couldn tell you the JHM rotors make a HUGE difference when combined with LW wheels. I’d say the wheels make a bigger impact, possibly because of the amount of weight farther from the center axis
the front rotors are just 10 lbs each = 20 vs. the 35 lbs you dropped with the wheels Joe, so there would certainly be a big difference just based on the weight alone with the wheels. It shouldn’t be surprising that the wheels felt a bigger change…whether that was due to distance from the rotating hub or not.
The rotors however when they were put on my car were definitely enough of a change that I said ‘wow’. That’s just 20lbs up front. So dropping nearly double that would be awesome.
I’m a fan of Jhm’s lw rotors but not for track use. I toasted a set on my s4 Avant in four months on tracks that don’t involve heavy braking! Daytona and Sebring would have crushed them, regardless they’re perfect for daily use spirited fun.
I have an Alcon BBK on my B7 so I’m limited to wheels/tires there. Though I can certainly feel the difference on the avant when I switch from the LM’s @ 23lbs to my track wheel/tire combo (Kosei’s) which weigh around 16lbs.
yeah, lots of the track day guys say they suck.
Personally, I wouldn’t take my daily driver to a road course. Nor would I take any 62/38 nose heavy family sedan to a road course…these are desgned to be autobahn stormers, not track day cars. Get a Boxster or something mid engined and 50:50 for the track is my opinion…they’re 100 times more fun. People make cracks about how these aren’t built for the dragstrip, but we’re using the dragstrip to measure acceleration, and the dragstrip is great for it. We’re there for a pass time, not a pastime. It’s an evaluative tool is all really.
These cars are 100 times less suitable for the road course than the dragstrip.
It’s funny how that works out. I’m sure guys love it though, so that’s all that matters. They should get some seat time in a mid engined sports car though…I reckon they’d ditch the Audi and change their mind real quick.
Very true! Daily driver + road courses isn’t a great idea, though I did track the b7 several times prior to the addition of the avant. It pushes hard thanks to the distribution you mention above.
The wagon certainly isn’t ideal either but it works in many ways from loading track gear to hauling damp golden retrievers to and from the beach all while being very capable on the track. The B7 has benefitted from the shared DD duties as it still is insanely clean, I might be nuts but it still smells new!
Dup post, deleted the 2nd
axel’s OZ wheels look solid. Big, 19, gunmetal (or really dirty) and light. Good combo. He has stoptechs up front.
^…let’s see the video you pulled that from!
Haha, of all the photos I have of my car, you had to pull a distorted video frame 
Too funny!
Here’s a couple better photos:
Funny! I thought your sled was bagged! Thanks for posting some better shots.
