[V8] Track F/R

[Jeremy Ward]

Jack,

 

Like Allen, I am running the H&R DRA style 25mm spacer, which includes
special bolts to bolt to your hub, and then you use your standard OEM lug
nuts to bolt to the DRA spacer:

In the rear, I am running the 15mm H&R DR style spacer, which requires new
ball-seat lugs that are 15mm longer than factory.

 

The Speedline A6 wheels I am running have an ET35mm offset, so I know I am
pushing it a bit.  I have a little bit of rubbing upfront with my new 245mm
wide tires.  :-)

 

Cheers,

 

- Jeremy

Makes sense- you lowered your roll center a fair bit going out that far- and
lessened the effective spring rate by making the lever arm that acts on the
strut effectively longer- and the farther out you go the more compounded the
effect is. 

Did you use at 50-53 mm lug bolts? I barely have enough engagement with 43
mm lug bolts (the longest I could find without resorting to studs) with 15
mm spacers? I would be careful if you did not, as you are increasing your
suspension loading with increased cornering forces.....no one wants wheels
flying off....

Even small changes can make a difference- buy having 25 out front and 15 in
the rear you added about ten mm of track out front, as the rear track is
about 30 mm wider from the factory.

Jack
