Legacybt 6mt Compromised Autocross Build

So nice! Are those STI cans? I' picked up a set localish, virtually brand new. I'm really happy with the sound, but they are tucked under pretty far, so tomorrow I'm off to get them extended 3". They still will be tucked

 

Thanks! No, it's a K2 Gear Spec-NeoDual exhaust - same as this one: http://legacygt.com/forums/showpost.php?p=4080760&postcount=5

 

It has adjustable tips, so I was able to slide them out to get the length I was looking for

Nice. I was looking at the K2 gear mid pipe a while back but got confused on the fitment on our cars. any modifications required? I think the JDM DP is a different length.

I have the full system so I don't know if it would bolt up to the stock cans, but I didn't have to make any modifications to fit it

I'm slowly picking away at my to-do list. I've never been happy with the way the JDM double din had an offset from the shifter surround, so I never even attached my trim pieces that run beside the radio. I finally figured out the modifications needed to get an OEM LHD fit, and I'm happy with the result.

 

Forgive the horrible photos, I'll upload clearer ones later. Modify the mounting tabs on the shifter surround where it meets the double din unit like so:

 

 

 

 

Elongate the metal holes in the radio mount (file away the left side of the holes on both sides, I never touched the plastic HVAC mounts - just left them unscrewed).

 

 

 

And voila!

 

 

 

Next step is to wrap the shifter surround with matte vinyl.

No promises on timeframe, but my 150,000 mile engine is getting tired and once it lets go there are going to be some fun things happening.

 

 

So shiny!

Fun things indeed!

Also almost have the motivation to finally put my din trim back together. Was doing a bit of stereo and gauge wiring and haven't finished putting it all back together yet.

Do it! It's lots of work but totally worth it once it's done.

I was wondering how the rear Brembo setup on the JDM/AUDM 'Tuned by STI' edition of the Legacy was set up, and through some JDM part diagrams and further digging, figured this stuff out:

 

- 190mm parking brake = uses 04 sti rear rotors (cheaper) and sti parking brake shoes

- Backing plate/dust shield sized to OEM sti rotors

- Rear brembo calipers (same as sti's) mount right up to the backing plate = no adapter needed

 

 

I bought some rear arms from Japan and confirmed the above.

 

Parking brake dimension (multiply by 2)

 

 

Caliper mounting bolt spacing:

 

 

I know you can get special parking brake shoes and achieve most of the same thing. I have a side project that justified the cost. Hopefully that info is useful to someone out there looking to do an extra-OEM rear Brembo conversion!

I installed this the other day!

 

 

I love how the seat felt on a short, fun drive. My knees weren't bruised from bracing against the door/console

 

However, I'm not sure I'm going to be able to live with it I have a feeling it'll destroy my back on a long drive. At 6'0 and 175ish, it forces me into some seriously bad posture. We'll see.

 

Another issue is that it sits slightly higher than the stock seat, meaning a helmet won't fit unless I'm leaned back. It might be time to re-bolster some stock seats instead.

I’m 5’9” and 145lbs so I don’t have the height/size issues. The odd thing is the right side JDM seat allows you to adjust height, but it seems to start at the same height as the left side JDM seat and then adjust you up to a crazy worthless height. I absolutely noticed the same thing about not having to brace yourself with your legs on the road trip I took last week and it made it so much more enjoyable to drive. You may be able to replace the foam in the seat bottom with something that is thinner/denser, like a memory foam, which would allow you to drop the seating position a little.

Yeah, it sounds like you're a much better fit for the seat. That's interesting, I was wondering what the deal was with the extra adjustability.

 

I'll look into adjusting the seat foam, but I might end up going back to a custom bolstered stock seat to retain OEM crashworthiness and to not have major questions from insurance in an accident. If this ever changes from a daily, however...

^^^ where did you find those?

very nice!!

Sourced them from the other side of the pond.

 

 

very nice!!

 

Thanks! I think I'm obligated to start taking the wagon to the track once these are installed. Spring rates are 13k front and 11k rear, I might have to drop them to something more streetable. Beggars can't be choosers though

Area27 ? Or whatever the new track is called?

So that's why you sold me the Ohlins [emoji38]

yes, id only drop the rear some. see if you keep the wheels on the ground under hard cornering with sticky tires.

I found these a couple weeks after selling those to you, the timing was perfect!

Noted, thanks. I'm running a 24mm front sway and 21mm rear too.

 

What are 13k springs like on the road? I still want to be able to enjoy the car on imperfect pavement.

well, assuming the valving in those shocks are still good and dont need a servicing, you might be alright with them. i found my old AST4100's to be much more compliant that a set of tein Flex's even though the ASTs had 50% stiffer springs. So it all comes down to valving. having said that, if you drive on roads that demand beyond the shock travel that you have, then it will be rough no matter how good the shocks/springs are, so keep that in mind. you may find you need less sway bar with these new shocks, at least in the rear.

I would love to head out there - they don't have many public track days but I'll try to get out and make it happen. When they do, the pricing is $$$

 

I'm working on the ol' 5x114.3 conversion and may have a abs-friendly solution. If so, track abuse will have to wait until after that's done. No promises though, it's been an open issue for a long time as you know all too well.

I have Erik's wagon which has his take on the STI conversion. The fronts are easy as literally swap the hub carrier and you're done. The rears are harder because of the hole location. His solution removed the abs sensor location.

 

I'll try to pull the trailing arm in the next 2 weeks.

You're building quite the collection of LGT's

 

I chatted with him about his approach to the swap - we'll see if I can carry on with the design I have in mind and incorporate the ABS sensor.

 

I have two sets of trailing arms sitting in the garage I'm working with - a steel set and a JDM spec B aluminum set with a Brembo-specific LGT backing plate to compare against. I'm all set as far as measurements go, and am working off manufacturer specs/drawings for the 08 sti hubs.

Nice. When you get it sorted, my sort of STI wagon will be upgraded
