Default Best model year for STU setup

So I'm looking to set up an STI to run in STU. From searching around I've got a pretty good idea of what mods to make once I aquire a vehicle, but wanted to get some opinons on if there is a particular model year that would be the best starting place. Any input is appreciated

Some seem to think the 06-07 had an improved center diff, and the 07+ I do believe had a longer 2nd gear. Either way its probably a toss up, good driving and setup is probably good enough, but whatever.

No one has really tried with the 08 yet, though... hard to say until someone does.

07 STI for the gearing.

05 STI for the better center diff that rotates the car and drive closer to a rwd car.

The steering rack changed in 05. Did it change again in 06?

Factory spec curb weight is 3298 05 and 3351 in 06, too, but I'm not sure where the weight came from. 07 lost the +caster front control arms, and I think also lost the aluminum rear lateral links.

I don't think it changed, but it did add SAS and Yaw Control.

The 06's can be made around 3100lbs in STU trim

My 05 in mild STU trim came in at 3170lbs. Still had stock headers, A/C, stock crank pully, heavy EVO2 exhaust, radio still installed, only 1 race seat (and not the lightest race seat) and not the lightest coilovers among other things. It had a quarter tank of gas at the time of weighing. Im sure I could get mine under 3100lbs easy!
Crash...what does yours come in at?

Oh and the steering rack is the same for 05+. 04 STi's have the lame steering rack.

Oh and to answer the OP. I say 05 and 06 are the best. But the 09's might take the crown...go with the 09!

With the AC. Mine at Nationals weighed in at 3154. That is with the AC, both stock seats, OE Battery, OE crank pulley, OE radio (with 6cds in it lol), and that was with a bit more than a 1/4 tank of fuel. I'm sure I could get mine to about 3070 if I really wanted.

2006 STU prepped STi
Sponsored by Agile Auto

Default

Bringing this thread back from the dead, rather than starting a new thread. I too am currently taking a serious look at an STi for STU next year. I'm leaning heavily towards a 2006 as I understand they drive similar to the 2005 with on throttle oversteer, while the 2007's lose that rear diff and have throttle lag, but get a longer 2nd gear.

With Nats moving for 2009 to a more open lot (Lincoln, NE anyone?), I'm in fear of getting screwed too much having to do 2-3 and 3-2 shifts. I recently sold my 2003 Spec V and I know all about short gearing and having to shift on long, open courses. But then again if it's so open that even the 2007's will need to shift, there's not too much disadvangtage.

I recently drove bdi's 2005 STi and LOVED the way it drove with the throttle oversteer and want to somewhat keep that aspect, but then again I don't want to get burned on the short gearing and wanted to hear the thoughts of others.

Of course...I could always get an Evo, but I would rather not replace clutches every other Pro Solo. And then there's the whole question of how long before 2008/2009 STi's/Evo's start running STU and will that make my decision to run an 06/07 STi pointless?

I'm considering both STi and Evo options, but I will say I had more fun in Iman's STi. And I do like the increased reliability factor of the STi over the Evo. Either way, STU is where I've decided I want to run next year. Just hoping that the newer Evo's/STi's and the 135 don't make my idea of buying an STi/Evo and prepping it for STU pointless.

I wouldn't be that worried about the newer Evo - it's really, really heavy. The newer STi should be very interesting though as it should have most of the benefits of the 07 and a better suspension design. (Then again, there's that whole "disposable engine" thing, hopefully that's fixed now)

I wouldn't worry about the new EVO or 135 causing any trouble in STU. The 09 STI might be marginally better than the other STIs, but I'm not sure if any good suspension bits are out for it yet so it might not matter. You know how I feel about the 08s >: (.

That mode is no good. You're better off with it fully off.
