I figure reinforcing can probably make the car more stable and somewhat easier to drive at cost of higher weight.

in theory yes... but if you can drive without, then enjoy the weight savings. same goes for brakes and wing.

Around the C-1 line, I'd recommend full reinforcement with highest brakes. The weight savings wouldn't help much since its lots of turns and braking.

The rear spoiler should be used based on your judgment. At high speeds, I would highly recommend having a rear spoiler on. Around the C-1, it may be advantageous to have the rear grip less, especially when driving a FWD car.

Some cars (I think you're driving an FC?) are just too underpowered and need that extra weight savings to beat the hardest bosses.

i'm driving an fd now and might switch to a ridox supra soon(not sure if I should or wait for another car to get unlocked and save money)

Well, the choice is totally up to you...but here's my opinion on the Ridox Supra: its the weakest of all the Special cars. The NOB Silvia will cut through corners like a knife, the West Corvette will go crazy top speed and the MCR Skyline will make short work of any car, anywhere.

I'd actually stick with the FD3S over the Ridox Supra. The engine swap will make the FD awesome, but be prepared to get smoked off the line against bosses, especially those with AWD. The FD can definitely hit 230 MPH (max speed for the game) and I personally like it because its the first car I used to beat this game (I went from the S14 to FD). Furthermore, isn't it more fun to have your own, customized car than drive someone else's? I always felt the game was more about making yourself and your machine into the "legend of the highway".

Do it on C1,but use the brake Level 4,to save weight. The Ridox Supra is crap. Wait for the MCR GT-R.

i havent really upgraded my brakes for awhile and only set downforce for rain. maybe i should start

If u don't upgrade the brakes, they won't stop the car in time no to lose SP. Jus a helpful tip.

I always reinforce. Always.

reinforcing is good DEPENDING on where ur driving and the nature of the car. The MR2 for example can use level 3 reinforcement on places with wide turns but on tricky places like C1 it needs level 5 cuz it will sort of "float" when cornering, resulting in serious understeer...and that happened even when i fully tuned it. Some cars can actually do fine with NO reinforcement at all, like the Lotus Europa with the turbo L6 swap; of course, it's fully tuned as well and it handles like a beaut on the C1 and anywhere else. But as a rule of thumb i suggest you use level 3 for straights/hi-speed turns, level 5 for highly technical areas. As for those who can do without, ya gotta do like me: just experiment with the cars and tune them cuz they will feel horrible if you dont mess with them but in the end it WILL be worth it...

Anyway i 4got to say that the benefits of lighter reinforcement on hi-speed sections is that the power-to-weight ratio will be smaller, meaning ull be able to accelerate faster and reach higher speeds, all while sacrificing stability but like i said tuning is possible to deal with this trade-off.

I always reinforce my cars.

think of going 230 MPH:
Then think of weaving through traffic at that speed.
Now, do you need control to weave or do you want to smash into a van?
The moral of that is reinforce to the area applicable.

True but it doesnt have to be level 5 im using level 3 on an RX7 with L6 swap i tuned it for use with no spoiler and it can consistently do 225 mph(no boost) and can go up to 229 on the furthest wangan in (the double downhill part-no boost as well).
As for weaving thru traffic at that speed that must mean that the person must have fell bak chasing whoever or is plain crazy cuz weaving with the turbo on messes with the car's balance(extra wheelspin) of course its gonna lose control even with level 5 reinforce thats why i barely use it...you should only use it when there's a clean straight. Or use level 1 or 2 instead of 3 cuz at 3 is when the wheelspin becomes more evident. 230 is nice but its unnecessary to beat ppl it all falls on the tuning again. If you can tune a Lotus Europa with turbo L6 and NO REINFORCE you can beat anyone in the game without even doing 217 mph.

Oh yeah, my RX7 weaves with control even without spoiler...tuning can make the impossible possible.

I never said it has to be lvl.5
It can be any level.

Lol got carried away. Best range is from none to level 3. But there's always some exception like the GT40-level 5. Well its the only one in my profile.

Almost the same here.
I do lvl.3-4 on most of my cars, except for the GT40.
lvl.5 all the way with that.

Reinforce lv.5 + Reduction lv.5 = My usual combo.

That works too.

i ussual use 5 reduction & normal reinforce..
i think thats good for cornering..
i use it on my mazda rx-7^^

It's not good for the body of the car, since I have found that the abilities of the car in question will fade if you smash into walls enough... I had to sell my MCR Skyline a few days ago and buy an new one...

My 180SX is wingless, has no reinforcement, level-1 brakes, and a turbo L6 swap. The car is unstable at 201+ mph, I have to plan when to brake to corner. If I smack a wall/divider or a van the car has little to no traction afterwards. So in a nutshell don't hit anything and your fine .

LOL, you have the same engine swap I have in mine.

I love that setup lol, I just say its an RB26. It spanked the the rook, bishop, and knight(thanks to retarded vans XD.) Just can't control the car in the rain after 30+ miles.

I beat the Rook, Knight, and Bishop with the MCR without them hitting any trucks/walls.

Yeah the rook and bishop got beaten without vans but I was starting to overheat by the time I got to the knight.
