I don't have much going on at work today so here are some of our upgrade options.
Tires:
245/40/17 seems to be the widest reasonably cheap tire size. RS3s are $157ea
Wheels:
XJR 17x8s should bolt up without issue and are in the low $105ea at Pacific Auto Salvage, Inc.
XK8 revolver 17x8s will require 8-10mm spacers but can be found for $85ea
Or we could go with a set of torque thrust knockoff 17x9s at $600 a set
Camber:
This is where things start to get tricky. The 98-03 XJ8 subframe has adjustable camber, but the engine mounts won't match up. I don't think it would be hard to fab up some new engine mounts, but we haven't proven to be the best fabricators.
Other options are custom machined upper control arms or custom bushings
Engine modifications:
The muffler delete is a given, not that it will add any power
Intake manifolds are an option
We have most of what we need to convert to the megasquirt engine management system
Turbos could possibly be installed
Headers are going to be a long term project
Weight reduction:
Thinning the wiring harness
Remove undercoating
Remove excess sheet metal
Less cheeseburgers
Steering:
The XJR has a faster steering rack that will bolt up
Brakes:
Fix the ABS
Manual transmission:
