I know this is a D street thread but where does a modified CTR go STX or STU?

DSP or STU depending on your mods of course.

STU seems to have a better pax modifier so that's where you'd want to go right? With just some 18" wheels and Hondata where does that send you?

The 18s and a hondata/Ktuner I believe puts you in DSP. If you go with a 19x8.5 1” smaller than oem and stay on the oem tune it’ll still keep you in DS.

Yea I have no interest in the wheels I know about that one, you can't run the Hondata tune in DS though? Either way just curious what the difference between being in DSP VS STU is

with no wider than 285 and no lower 200 tr tires you'll be STU legal.

Perfect! Thank ya

STU, DSP is Hoosier class

Ohhh so DSP I can run some A7s and trying going real fast huh. Good to know if I get into it more.

 

[RacingManiac]

Probably more fun to go SMF, but it might be more competitive in DSP

 

[bouford]

yup, prepared cars are usually are on r-comps.

race tires are fun but an added expense. Im so glad the Stock class days are over! My 1st year at nats in my 2010 cobalt turbo, my codriver and i corded, CORDED, a new pair of front hoosiers.

I have a 2019 CTR and plan to compete in SCCA DS class. I am planning on running Motegi MR924 wheels with 71Rs. Conventional wisdom says you should stay with a tread width that is close to the rim width. I am leaning toward 255/35/19, but am interested to find out if anybody has directly compared the 255's with the 265's. I need to get them ordered and I don't want to spend the extra $1k to buy both 255 and 265 for the front.

either will work for you. i run 255s on my18 since our courses in hawaii are typically 30-40 seconds, tight and slow speed. i also rotate tires after every race for even wear. gl!

I see you are using the Karcepts rear sway bar. What settings do you prefer? I envy you doing autocross in Jan! It was -26 F here last week!
