  1. Michigan Sold: Sold: Acuity short shifter and shift boot collar for 10th gen Civic

    Both are in perfect condition. About 5000 miles of shifting on them. I though the shifter was fantastic. Alas, the car has been sold and the new owner wanted the factory shifter. $370 for both, shipped via USPS in the continental US.
  2. Michigan FS : 16" Borbet Wheels & Sottozero Winter Tires for 10th gen Civic

    $300 Local pickup only in SE Michigan My Civic is sold. I still have a set of gray Borbet winter wheels & Sottozero-3 215/55R16 tires. Tires have 5/32 and 7/32 tread, about 5500 miles on them. The tires are not very good winter tires, but are considerably better than the factory all seasons.
  3. Lesson Learned...

    Maybe it's just me, but if it eats plastic I don't want to inhale it.
  4. Si's Helical LSD - Locking and Unlocking in fast turns

    I think dual axis struts are designed to minimize the offset between the steering axis and the center of the wheel, which in turn minimizes torque steer. lots of roll stiffness and lots of negative camber makes sense. I would distribute the additional roll stiffness between front and rear...
  5. Snow tires? or high performance all-seasons?

    Whatever you get, avoid the Pirelli Sottozero winter tires. Not sure how they got the label 'winter' or how they got a good rating on tire rack, but I have a set on my Civic and they are gripless in snow. I'd rate them equivalent to the bottom 1/2 of the all-season tires I've had over the...
  6. Designing lower control arm mounted air deflectors for brake cooling

    I bet they work well. I ran Porsche 993 air deflectors on my 911 for a decade of track use, and they did a dandy job keeping the brakes cool. The 993 pieces used to be semi-cheap (30 ea), might even be adaptable to the Civic. Many folks just zip tied them to the control arm ... mine were a...
  7. Show me your aftermarket shift knob

    I have the Acuity shifter with a wood shift knob, and I think it is fantastic. Shiftknobs are a bit of a hobby for me ... if I thought a heavier shift knob would make the shifter feel better, I'd simply make one. But I think it would just muddy up the feedback from the shifter & transmission...
  8. Spoon Motion Control Beam for the 10th gen

    Huh ... this smells like snake oil to me. The only time I have seen spring/damper units used in chassis structure is as tuned mass dampers, where a very specific frequency of a structure is being tuned out to get rid of a shake or vibration issue that irritates customers. Generally one end...
  9. "Fun" cars vs Civic hatch/Si

    I came from an old 911 and a Saturn Astra. No canyon runs, but 12 years of track driving. I've driven a spec Miata on track and loved it. I find the sport hatch to be ... ok. It feels weird and nonlinear when driven above 4/10ths. And I mean everything - throttle response, steering, braking...
  10. Anti-oversteer

    I don't consider it a cheat code - I think it is really intrusive when the stability control kicks in. It seems overly aggressive. Also it does not seem to recognize that opposite lock has already been applied, and it then fights the driver's inputs. The Civic does seem to have a relatively...
  11. Si's Helical LSD - Locking and Unlocking in fast turns

    I have zero experience tracking FWD cars. Still, I would think a bigger front anti roll bar would be detrimental in a FWD car. A stiffer bar will unload the inside front tire more than a less stiff bar - this seems directionally incorrect. Lots of cars lift front tires - old 911's readily do...
  12. Keep or quit?

    A few thoughts. 1) If you are a habitual modder, you can buy something more expensive and you will still mod it. Except modding parts will be more expensive as well... so now you are spending more to mod a more expensive car, which depreciates more because you are modding it... 2) No matter...
  13. Warped Rotors at 10500 miles?

    In my experience, 'warped rotors' are often not warped. Instead, the pulsation comes from uneven pad material transfer to the rotor, causing a varying friction coefficient. Horrible Freight sells perfectly usable dial indicators for a song, should be easy to measure runout of the rotor. If...
  14. Aluminum Lug Nuts?

    Air cooled 911's all came with aluminum lug nuts from the factory, and they work just fine, even on track. They do need anti seize on the threads and the contact face every time they get removed & replaced. Most track folks replace them with steel sooner or later. They have a quarter-round...

  16. 10th Gen Fk5 Hatchback Sway bar and endlings

    What specifically do you want to improve? "Better Handling" is a really vague goal ... Not sure why stiffer springs would need softer anti roll bars and vice versa?
  17. Type R Fail. #Submitted #Denied #Unknown

    Just to add to the pointless speculation... :) Damage from a non-catastrophic mechanical overrev can take 1000's of miles to manifest itself. If the overrev stretched the rod bolts, they lose clamp load, and at that point start accumulating fatigue damage. Eventually they initiate a crack...
  18. Going to the track with a Civic Sport

    A Sport Civic is a fine car for a track introduction. You will be the limiting factor, not the car. Leave your ego at home, and pick a group with in-car instruction. Learn its limits, *then* spend money to move the limits. The nut behind the wheel will be the limit for a while - so spend...
