Another one of my attempts to get cars you don’t see that often to go fast, one especially close to my heart as I own one of these…1st this is FWD as there’s too much power and not enough tyre to balance RWD. Unless you nail the throttle and light the tyres out of slow corners it still turns in pretty good for an FWD though and it has a reasonable range of use. Times wise in Europe I’m 743 on Prague full (2:15:128) 455 on Nurburgring GP (2:21:854) 267 on Sonoma Short (1:26:178) 429 on Sonoma GP (1:49:009) 916 on Brands Hatch GP (1:42:737) and 527 on Bathurst (2:30:627)

I had been making good progress with it but think i may have reached my talent limit again with it, not sure the build is the best it could be it needs tweaking but at the moment any changes I’m making are going slower so a fresh pair of eyes and some new ideas would be appreciated and definitely helped with my earlier Astra.
.
When I read your intent of pulling together the Mazda 3 in your previous (Astra) thread, I actually built one up, yet, did not tune it…thus, I’ll compare notes.
Just a quick look at your build…you can get rid of an add’l 6 lbs with the Street Hood (unless you do not like it), or, 1.8 lbs from the Street Driveline. Or, 5 lbs less with the rear rim down to 19"
You can also upgrade the Rear tire width for FREE, though an add’l 4 lbs, this can be offset nay the above. Add’l H & B.
Or, any combo…you can get weight down to 3217 lbs
.
I shall try these now as I’ll be on for the next few hours.
Weight wise originally I tuned it with stock engine and fully lightened (effectively a full handling build) but at the time I seemed to go faster with a more powerful engine and more tyre instead of lighter weight I will go back to it though.
Regards where I’m tuning for originally I wanted an all round car that I could use in C lobbies (much like the Astra is now my D lobbies car). That’s kinda why it’s a much power as you can get away with while being able to turn (ish).
.
There is also a build which you can get rid of the tranny upgrade and get Race Springs. Depending on what tracks you are targeting it might be worthwhile, or get more power and/or weight out.
So I tried out your build and tune, and it drove quite well, I was able to pretty much match your laptimes.
Since the car drives like a tank, though, due to its weight, I wanted to try to make a lighter weight build. By no means am I trying to highjack your thread, but if you want to try this:

My times on Nurburgring GP were almost exactly the same as your car, Bathurst (yuck) mine was slightly faster at 2:30.292, Brands Hatch GP mine was slightly faster at 1:42.438, and Sonoma GP mine was faster at 1:48.126. I also want to disclaim that I’m only an average driver, and none of those tracks are really my “good” tracks.
I still think your build/tune would be faster on tracks where outright speed is more important.
If you swap around a couple of parts and get rid of the Sport Tranny (which you really do not need) and the Street Chassis, you could get down to 2706 lbs with 276 HP, 294 lb-ft (Race Valves).
.
Good job on the build and suggestions Punch! Since you ran 4 of the tracks mentioned by OP, I went ahead and ran the car at Prague Full with the 3214 build I mentioned above and was able to get a 2:14.549 on the 2nd lap (and tune could use some work…esp ARBs for the FWD). The ghost at that weight level was way to slow up the hill and that is where I over took. Anyway, there are several ways to potentially improve and/or leave as is…to your point, it really depends where one would want to run this car. Can have several setups for it (les weight, same weight more power, etc…).
PRKid
p.s. If I get a chance I will re-run at Prague with the several builds mentioned.
p.s. #2 I did not realize it, yet, this car does not get run a lot…just saw that it might be potentially the top Mazda 3 within the Division @ Prague Full. So, room for improvement certainly.
.
.
OK, so lowest I could go in Weight would be 2671 lbs…no Stock Tranny, No Chassis, Race Brakes, rims 19/19, Sport Ignition. Stats: 5.6/5.1/7.3/5.1, 272/289, 2671 (57%)
Gave it a 6 lap run for a 2:12.621 (AM 178, WW 643, Div 173, #1 Mazda 3). Had several 12.2’s, so should be capable of 11.x’s and lower for a good driver.
.
OK first of all Tried the Falcon Punch build. I can’t drive it I’m afraid (no offense intended I need a certain amount of front end grip in a car for my driving style to work and when I drive it all it’ll do for me is push wide so didn’t manage to set any good times). I can see where you are going with it so I’ve had a bit of a build which is a hybrid of Falcon punch and Prkid directions with some tuning I’ve borrowed from my V6 one. It is slower by nearly a full 2 seconds on bathurst and about .5 sec slower on Nurburg gp as the barn door wing settings and lack of V6 kill it on the straight but I’ve got a 2:12:515 on Prague on my 3rd lap and beaten my times on Sonoma and Brands by reasonable margins. 1:48:267 on Sonoma gp 1:25:957 on Sonoma short, 1:42:639 on brands GP.

Think it comes out at 268 horses and 2644 LBS 57% weight front.
Glad you proved your lap times at 4 tracks out of six with the brainstorming here. As we mentioned before, it really depends for the tracks and Bathurst is certainly out of the list from the other tracks as far as what you need to be successful if what you want is LB improvements. For lobbies, you can manage with the less power/speed build.
No offense taken! Everyone has their own style of driving, and I know exactly what you mean about it pushing. I have a feeling I’ve been looking at things completely wrong on FWD suspension tuning.
I had originally built the MS3 without a rear wing as an attempt to keep more straightaway speed, but the car simply lacked grunt with that build. I may try some more variations today.
Alright, so I’ve been messing with this more (thanks for the distraction!) and it seems that in true Forza fashion, more power is more better.
Nurburgring GP 2:21.0xx
Brands Hatch GP 1:41.8xx
Bathurst 2:29.0xx
Sonoma GP 1:47.8xx
Prague Full 2:11.2xx
Watkins Glen Full 2:08.8xx
The tune definitely needs some work, mainly in the understeer department (quite evident on Prague)

Nice job Punch…interesting since this is very similar to the first build I had put together based on the Astra thread we had before, yet, never put a tune on it nor ran it/tested. …lol…
I’ll put it back on the testing rout and post as well.
For some reason in forza the path to speed seems to lie with as much power as possible and as little handling as you can get away with except the few tight tracks.
I’ll build yours tonight and see what I can do about the push.
Yes, very much so, and I find that rather upsetting.
Also, if you can help me figure out what I’m doing wrong that’s giving me so much understeer, I’d very much appreciate it, I’ve a few more cars in my garage that could benefit greatly.
Part of it is running a car with with FWD and 60% weight front it’s always going to push a bit. It’s made worse by the oversized rear tyres meaning the front will always want to let go first!
My attempt to make a difference, which has beaten my times on Brands, Sonoma gp and Prague. Haven’t touched the build and haven’t redone all the settings either just tweaks here and there.
