geometry guru's help!
Hi there.
Before we start, many thanks for you that have something proactive to say (
), but for the others please don't whine about what i have on the car, as that's very much 'my choice'. Suggestions to remove & go for XXX is a waste of time and will probably result in a Mrs Browns Boys style "thats nice" ...
Have a Blob WRX & need some input with regards to geometry on revised suspension. The following suspension mods are from standard:
1. Tien-S springs:
Spring Rate (04-07 WRX): F 252lb/in R 219 lb/in
Drop (04-07 WRX) F 2.2in R 1.7in
2. Whiteline 27mm rear ARB, 24mm front (yes they are stiff but suit my needs
).
3. Whiteline ALK
4. Whiteline front and rear solid drop links
5. various poly bushes
The struts are A1 etc...sat on 17" wheels (OZ P1)
Looking for geometry settings, will the Prodrive suffice or should i be looking at something more radical...the car is fast road/odd track day etc...
Cheers all...

What power and tyres are you running?
What characteristics do you prefer?
For track you want as much as you can get of everything except toe, on the road you'll want less camber to maintain a bigger contact patch as you'll be going slower, though I doubt you'll have much roll with those bars, It may even be quite skittish and slower dare I say.
You may want to consider camber bolts or adjustable top hats to get more caster and camber.
Have a read of this thread.

P.S I do most of the actual work myself and the local tyre guy operates the computer and sets everything up, depending on how much time it takes and if he has to break out the blow torch I pay him between £15 & £20 which is about a days pay out here in Croatia for most workers and about twice what you earn at the car wash.

I think it's all down to personal preference tbh, personally have roughly the same sort of set up apart from coilovers and slightly smaller RARB and wider wheels. I've had both my cars set to Prodrive settings by Mototec in Blackwood but you'll need a pair of rear camber bolts and both cars feel very planted through the bends when pushed hard and personally I have no complaints at all with this set up.
