what i meant by "easy to drive" included having to drive at low speeds, stop and go, etc. Our cars can easily be creeping at like 3mph without needing the clutch pedal work. my place has an insane driveway ramp upwards and then sidewalk and immediately down to the street basically being a giant speedbump. i scrape for sure, but i try to minimize the scrape as much as possible. slip the clutch to get to like 2-3mph and after that its just slight throttle control.

MOVE !

There is no better car out there. There are better living/parking situations.

Additionally...you won't own this car for long without scraping it's front end once in a while...it's inevitable.

I personally have no problems with the car being "clunky" at low speeds.
Car doesn't have a heavy clutch, a grabby clutch, or much torque...

The problem with your setup is you have soft springs, soft shocks, reduced travel and lowered too much for the spring rate. I'm on coilovers adjusted lower than any springs go and never have problems bottoming out at low speeds.

I would slip the clutch because lurching causes damage to the entire drive-line of the car (i.e., engine to the transmission to the wheels, basically entire structure of the car).

I can live with that. Already scraped a few times, but doesn't hurt to minimize that count.

It actually only lurches on cold starts, even after a few minutes warming up the engine (presumably because the rest of the car is still cold). But, I'll go with slipping the clutch as if I were reversing out of a parking spot.

Slipping at low speeds > lugging

I welcome you to try the 6 speedbumps in my complex...I'll take pictures later..

regardless, bottoming out was poor wording on my part as my setup has never truly bottomed out, but yes the soft shocks are indeed causing the chassis to rebound enough to hit the bump though I don't think the lowering springs have affected me too much as my first FRS at the stock ride height hit the bump just as often....and you're right, coilovers would avoid such a bounce but for DDing that is like the only benefit lol (besides better stance)..nty..not to mention I would have to initially drive slower over these bumps too

Use more revs and slip the clutch when the engine is cold.

Slipping clutches is part of life, just don't ride the clutch once you're over the danger stall zone as that will wear your clutch quickly.

I would take a small amount of clutch modulation over lurching / lugging. You will learn to feel it out over time.

From what I have been told, it's alright to slip the clutch at low speeds and low revs for a short time.


Another trick is to blip the throttle a bit then modulating the clutch to control the speed.


I am also working on my stick skills, too. Looking to learn how to heel and toe this summer.


I think a nightmare situation for me would be to parallel park on a steep incline, especially since I don't have power steering haha.

Constant revs when slipping the clutch to stop the jerking or wanting to stall.. similar to a hill start or when crawling in traffic going up a hill.

Id slip the clutch. My driveway is garbage and has a wierd crown so I have to go very slowly to avoid scraping when there are 2 people in the car. But if you work on super small pedal inputs it can be driven that slowly without the clutch, just takes a fair amount of practice
