My list...
...based on tuning and floggin a few Xs over the years.
Ergo...a field tested list, based on stated goals.
More emphasis on competition driving would create different list.
1. Fresh rubber, no doubt.
I'm outta the loop on current particulars,
but previously ran Spec Racer Ford DOT race tires...Yoko, BFG, & Toyo variations.
Harsher ride, tread life limited to few thousand miles.
No other mod will create as dramatic an improvement in grip.
And improved steering response of stiff sidewalls.
Takeoffs readily available for cheap.
Scuffs can be found for pair'o c-notes.
You'll feel like you have big red "S" on your chest.
Less radical, but far more grip than normal rubber is high pro street rubber.
This category has dwindled to near extinction in our size.
Again, I'm outta the current loop,
but the Toyo has maintained production of our size.
Similar attributes of Spec Racer rubber, but more civilized.
Except the price...600 simolians.
Yikes.
For typical hobby X,
normal steet rubber will still show tread depth
long after reaching an age where replacement is prudent.
Just like trailer tires...it ain't the miles...it's the age
that defines end of life.
Cost a few hundred $ more that normal street rubber,
but in macro picture,
mere pennies ADDITIONAL than simple rim protector rubber.
2. Insure all OE suspension/steering/brake components are in good nick.
Replace as needed.
3. Performance alignment.
Insure caster/camber are same each side.
Use settings towards maximum positive caster and maximum negative camber of spec range.
Toe setting opinions are like belly buttons.
Definitely less toe in on front than specs call for.
Notice focus thus far is optimizing OE characteristics.
As stated, OE is great lil' package as-is.
Now...if you wanna spend money on speed parts and bragging rights, read on...
4. KYB Gr2 struts. If OE hydraulic struts are worn out,
new gas struts will restore worn dampening,
improve it somewhat over hydraulic replacements,
still ride decently,
and cost far less than other performanc struts.
5. Improve springs. Two different approches:
Option 1: Install cut rear springs on front.
Minimal cost, improved steering response, reduced body roll,
harsher ride due to changing OE front/rear balance.
Option 2. IAP/Vicks lowering springs.
Downside is tariff...300 simolians,
but all the performance improvements of cut rears,
plus provides better ride.
They don't change OE "nose high" attitude.
For comfortable ride, install as purchased.
Optionally, cut fronts to improve stance.
If you don't cut front springs, install Plaia pivots at the same time.
They reduce steering effort nicely, and are inexpensive.
Can be made to work with properly cut springs and TLC.
6. Install front swaybar.
I ran upgraded spring/strut combo for couple years.
Then added sway bar.
Made me a believer...to further enhance
a basic street suspension.
That's as far as I'd take suspension
for hobby car that doesn't see much competition use.
At that point, engine mods would be in order.
But that's another thread...
