Hahahaha...that too

 

I have driven the same long route to the hill country in Texas with my M3 and now with the new stang and the M3 handles corners as if on rails and rarely breaks out the rear. Where the Mustang hops sideways once in the air. I wish I could get rid of that

 

Correct, straight line racing a IRS will not beat a solid rear axle, it is only on curves when a bump in the road comes along and the IRS will beat it any day

 

But the SRA IS the only weak link in the Mustang when compared to the M3. The M3 and Mustang are so close in straight line perfomance (since i have owned both) that cornering is the Mustang's weakness when compared to the M3. I know comparing BMW to Ford is hard for me, but there is only so much you can do to a SRA where the IRS will shine so easily over a SRA.

 

If you watch the video, it was originally designed for the Mustang for Ford, Ford just never used it. http://www.mustangirs.com/
It is pretty much the only thing you are going to find for our cars.

 

Ridiculous. Quit being a panzy afraid the rear end is going to lose the corner just because of a bump. Keep your foot on the pedal and you keep your traction. Let the suspension work - don't freak out. Plenty of people can drive the hell out of an SRA on a two lane twisty friend. Bumps and all. If you're afraid of Texas hill country you better stay away from narrow bumpy mountain roads that have no shoulder. Guys like you crack me up.

 

There is a reason why the sra is an exception not the rule for sports cars. That said, I believe the sra is a blast to drive. I purchased my car knowing that the new mustang coming out would have Irs. It's pretty amazing that ford has made a system that shouldn't work, work in such an impressive way. The sra makes you work more but the nothing is as fun to drive.

 

OP you have the FRPP adjustable handling pack, so how do you have it set? You could be hopping around because the ear is set too stiff.

 

Base GT is right behind the M3 on the track, all others out run it on most tracks. On back roads and track minor mods can be made and you won't notice the difference. On extremely bumpy pavement the IRS has an advantage. Get good tires, shocks, struts and springs. And you'll be able to drive the car harder with confidence.

 

Panzy....good one. I can drive the hell out of anything. I am a retired driving instructor. I sure I could out drive you any day, but that is another conversation.

But it is just numbers I was looking and striving to make it better. The FR adjustable suspension is better then the Track Pack that came on it. On a level curve it can handle its own now with the upgrade. I can just tell the difference in handling since I took the M3 and the stang on the exact same route in the hill country. When the rear end in the mustang hits the air because one tire hit a bump it kicks sideways when the M3 never did.

 

It is definitely fun to drive. I know Michelin SS would give it better grip and maybe staggered tires with maybe a little wider tire in the back

 

No, it shouldn't be set too stiff. Because I still have 3 turns to make them stiffer. The stiffest setting would be reserved for a track. But I am going to try some different settings and take the same route again to see what differences I can notice

 

I know on a straight line the M3 and base new GT are right even, maybe the stang a nose faster on a good day. But for sure if there are no bumps to make the back end leave the ground, with my FR adjustable suspension setup, it should be even with the M3 if not better. I like how the FR has lowered the suspension an inch. You can tell the difference between the Track Pack. I like how the FR has infinite settings where as the M3 only had 3 settings.

 

I am sure if you set up the Mustang, even on a bumpy road, it would out handle an M3. You may have to sink some money into it but no were near the extra 40k price tag of an M3.

 

I have the whiteline panhard bar with brace (along with several other goodies) and I do not notice irregularities in turning left vs right - also the rear end stays planted under heavy accel. If there is wheel hop, then it is a very smooth transition in the from of wheel spin, as I get zero vibration when the tires do break loose.

This is my first SRA car after having owned several 300HP+ MR2s and a well equipped 2007 S2000. I do not feel that the lack of IRS is in any way inhibiting performance in any particular situation - and I'm mainly a road course driver.

 

Exactly - I guess when those Cobras and Boss 302 Mustangs dominated race tracks back in the day those were just 'primitive' times - they clearly don't have the god-like benefits that the all independent suspension has blessed us with!



Face it - squeaks bumps unsettling - are only problems if you're used to driving Accords and Camrys your entire life. If you don't know what to do when your rear end starts complaining perhaps you shouldn't be playing in this game?

 

The Brembo packaged GT already beats the M3 around a track so with the FRPP suspension, which I believe is the P springs and the Tokico D specs, it would pull even further ahead of an M3.

 

Are you guys serious, giving him a hard time about the SRA hopping? There's a reason only one car in production today has one. Regardless of how great a job the Ford engineers have done making it work (and they've done a great job), there's no denying it's an inferior setup for most everything except drag racing, and it definitely is for normal street driving. It's a compromise I knew about and was ok with when I bought my car, but not a day goes by I don't notice it at least once.

 

My only reason for giving him a hard time is because he acts like the SRA is a crutch holding him back, instead of learning the qwerks he just wants to change it. And if it is so inferior and only good for drag racing then why does the 302S demolish in the World Challenge series? It just seems like another MT-82 thread where people ***** and moan and say the only thing they can do is replace the trans because it's just too hard to learn. Now if OP was Randy Popst and told me the SRA was holding him back, then I would out a little more stock into his decision.

 

Except! Even Randy Popst said in one of the Boss vs Camaro comparisons, that an IRS can't put down the power as well as the Live Axle coming out of a turn.
If need be, i can try and find which video it was.

The IRS would make it better on a back road where there are bumps but it isn't necessarily a complete better set-up, just different. Both have pros and cons. I think track wise though, where the road is smooth, SRA-for the Mustang. Touring, IRS.
