Cov that does look fantastic on the 20's :thumbs:

Cheers for the input fellas, I think I'll do the best I can to get it set even and then the place that does the alignment I'm gonna use also does corner weighting so will see what they say.

Double checked and the drivers side was a couple of mm lower so have compensated for that today and it is alot better :mrgreen:

With the Hundreds of cars we have lowered over the years and having been in the suspension industry for 30 Years , i am yet to get a defining answer from manufacturers as to how far out the ride heights on standard cars ( from left to right ) has to be before they would call it an issue . BMW said anything less than 12 mm they consider normal. Of course on a lowered car 12mm will immediately make the car LOOK cock eye . .
The RS4 type chassis is most definately much easier to corner balance up perfectly compared to say a GOLF R or Audi S3 for obvious reasons . ( engine and motor in one corner )
Covkiller, did you balance the car to move weight forwards or rear wards, or to accomodate your weight ? what improvement did you feel after ?
What i was trying to say in the earlier statement is that a Standard RS4 should balance up perfect with the coil overs set at identical height from left to right , If adjustments were made to include the driver then normally the N S strut would be pretensioned to balance the drivers weight over to the N S .
My personal Race cars would be corner weighted to each track to increase grip on the wheel more likely to spin on exit of the corners . As always you will sometimes forfeit a few corners to improve a greater number of corners . we didnt corner weight to achive identical weight on each corner however as this might not be ideal on every track.
I agree that suspension set ups are very emotional and personal , not everyone is looking to achive the same results . One mans comfort is another mans poor handling car . One great handling car is another mans harsher ride nightmare .

is shifting the weight the reason Audi only lowered the rear of the SS+ cars?

My car is focused to shift weight forward and corner weighted with my weight in the drivers seat and weights in the boot to represent a full tank of fuel. After tuning my car felt more focused and confident, turned in more sharply and handled at speed through bends better by a vast margin. Going round and round a roundabout showed the understeer had gone. On a bumpy road it felt more stable too.

Looks good there, Doug’s shared a few pictures of epic machines. Plus one of the monster trucks fell over, lol

Thanks for posting. Might want to blank out the vin though. What are the corner weight measurements?
