throwing SRT4 rear sway bar and stock spring/struts on stock

Have some questions about how to achive better handling and stopping power using different springs, upgrading to coilovers, questions on swaybars, bushings, different rotors, pads, ect... Having any steering problems or questions about steering racks, tie rods, tie rod ends, ect... ask these questions here.

throwing SRT4 rear sway bar and stock spring/struts on stock

Post by greybox » Thu Aug 04, 2011 5:25 pm

Yes I have searched everywhere and get some answers, some not...

If I throw a set of stock SRT4 springs and struts on my 2000 neon...it will lower it about 1/2 inch and add more aggressive spring rates so it should corner better right? (as well as giving me slightly more clearance for taller tires due to the strut perches)

The rear stock SRT4 sway bar is thicker right? This should aid on making the car turn in better and dial out some oversteer (because a stiffer rear sway bar does that) is there anything different about the end links or end bushings where I couldn't just bolt this in even without the SRT4 struts (I have a factory sway bar now)

so...the other questions...is there anything that connects to the struts as far as control arms/knuckles etc where the SRT4 struts won't just bolt right in?

Thanks

I have searched and searched and researched...so if I get a full SRT4 suspension it bolts right up...front might stay the same but rear drops like 1/2 inch...so if I get these I get the option of fitting slightly taller tires and I do get better suspension feel especially when it comes to a sporty feel...and if I get aftermarket springs for a regular neon (say with a 1.7 inch drop) I will actually only see 1.3 inches due to the SRT4 spring perches being 10mm higher -right?

-Yes, it will all bolt in.

-An SRT rear sway bar is 17mm, and I believe yours is 15mm, though there have been inconsistencies from year to year so it would be best to measure it with a micrometer or dial caliper. Endlinks and bushings are interchangeable and it is not necessary to get shorter ones due to the minimal change in ride height.

-Not positive on the final ride height with the SRT suspension, but your info sounds reasonable given the measurements. From the pics I've seen of cars with the SRT stuff, the difference is almost unnoticeable.

-Yes, using Neon springs on SRT struts will yield less drop than advertised.

For the record, larger rear sway bars will increase oversteer, and when tuned right will indeed increase handling performance and grip under lateral loads. The difference between 2mm is minimal, especially when coupled with stock SRT springs and struts. The SRT spring rates are only marginally higher than non-SRT units, with the struts valved accordingly. You can expect an extremely mild increase in overall handling performance.

yup-typed it wrong...bigger rear is more oversteer which is what I meant to say...car does tend to understeer as it is so I need to do some tuning...bigger rear sway w poly bushings should help a bit I am thinking

It won't so much get rid of understeer as it will add oversteer. I've found that even with extensive suspension tuning, these cars will understeer under acceleration when pushed to the limit. It's just a characteristic of a front heavy FWD car really. The scary part about loosening up the rear of these cars is their tendency to oversteer VERY aggressively under braking while near the limit of grip. This characteristic is magnified unless you balance it out with a few other complimentary items, such as DCR lateral arms, which help a TON with the brake oversteer issue. For me, I like being able to rotate the rear with throttle lift, but still be able to nail the brakes while cornering without being gun shy. Of course, if I'm going fast enough and braking hard enough, there's no avoiding losing the rear end. It's all a matter of thresholds.
