Thanks for the info Brian. Should I shorten the shock body to achieve the 13.25" and leave the preload where it is? Then play with everything from that point forward?

Thanks

That's about it. Release preload first...then just spin entire shock down into the bottom coupler after release of the lock ring against that coupler. Lower about half an inch into that coupler. Then lock the lock ring, reset the spring preload.

Question: Should I be running stiffer springs for more serious competition? What rate?

I'm running Dunlop 255's all around and at 13.25" the fronts rub the fenders when autocrossing.
Just raised it to 13.5", did 1 event and seems fine.

I was at the Packwood National event in Washington and got my but kicked on the first day but gained a few spots on the second. Quit the learning experience!
Being used to consistent top 3 finishes on local smaller parking lot courses did not prepare me for the wide open and fast flowing courses in Packwood. Running up against some very experienced drivers and well prepared STR cars (non of which were hard tops which I believe are 125-150lbs lighter(?)) made it a challenge and a learning experience.

Guys have turned top results on the standard setup so it hard to say you 'need' higher rates. As I tell folks all the time, it is also very important to tune the car to the surface you run most. If local surface smooth you can go higher, but if local surface rough (like here in San Diego) then higher can mean less speed as the car skitters around on the rough surface.

I will save my money. Thanks Brian!

Do you know the actual weight difference between an NC hard top and soft top convertible equally equipped?
How much of a difference do you think it makes on a 60 sec run?

Front adjuster does not fit under shock tower brace

Postby LarryL926 » Tue Jul 29, 2014 10:05 pm

I am a newbie at this so tell me if I am off but the adjusters on front coilovers do not fit under the stock shock tower brace. I do not see anyway to make them fit. 07 Grand touring w/appearance and handling pkg. Do I try to drill a hole in the top cup? A small hole and use the extra adjuster knob with the extended shaft or a bigger hole to fit the standard adjuster plus nut through the top? Or did I miss something obvious???? When I try to place the brace on the studs it is sitting on the top of the adjuster right about where the corner of the bar hits the cup.

Hi Larry

We just take a hole saw to that and make a hole.....it won't impact performance a bit. Finish up with a shot of rattle can black gloss and it looks factory!

OR...you upgrade to one of our nice aftermarket choices that already have that top bit open.

Brian I got the backs on, maybe took 2 hours, but I did it by puttingthe shock onto lower mount and jack the whole assembly up and attached the top stuff and didn't remove the top hat at all..... :|

Oh how big of hole did you drill in the tower brace? 1" I'm guessing.

Hmm,
Remove the alloy adjusting knob from the shock. Now use a few pieces of masking tape under the tower brace. Now try to place the brace where it will mount once a hole is drilled. Take your time to line it up the best you can. The top of the shock shaft should put a mark in the masking tape once you put a *little* pressure against the tape. Now use a center punch and a smaller drill bit to drill a starting hole, I used a 1/8" bit. After you drill the starter hole remove the tape & place the brace back to see if your off oneway or another. I then use a 7/8" step drill bit to enlarge the hole. Now use a small round file to clean up the metal burrs & some black touchup paint to paint the fresh hole. If your not centered fairly well you may need a larger hole. Touchup auto paint can be pickup for about $5 to $7 the step drill bit can be pickup from go old HF for about $3 to $5. :idea: You can just use the step bit to drill the starter hole too.

Brian -- can you help me understand more about the Swift thrust sheets? I've noticed that some people need them for the Ohlins, while others (perhaps most) do not. Under what circumstances are they needed? I'm expecting my set to arrive soon and I'm wondering if I need to consider these things.

It is a big plastic washer. My estimate is perhaps 1 out of 40 customers get them. They simply reduce potential for noise. In performance coilovers like these the springs are in direct contact with the metal perch, no thick rubber gasket like in most stock setups...and that metal to metal contact means some potential for squeaks as the system compresses and the spring releases again...and that thrust sheet is simply an isolator to avoid that metal to metal noise potential. I have not found the need, most customer don't, but if you are particularly sensitive to every sound you hear in the car then you might like to include those.
