So I made a TII swap into my NA 88. I have 16" Konig wheels and OEM size tires like the TII and I'm pretty sure my speedo is off. It shows about 130km/h when I'm actually going 120km/h. I have the GXL LSD, is that why? And to fix this, should I get bigger tires? Right now I have 205/55/R16. So should I go 215/55/R16? Or 205/60/R16?

Thank you.

 

I have that same problem. Did you swap clusters? Since they are different. THink the n/a goes to 160 and tii goes to 180.

 

No, both go up to the same speed.

 

N/A 150
T II 160

is the wheel/tire combo the same size for n/a and tII?

N/A's have 15in. wheels therefore if you did not swap the clusters you wont have a accurate reading.

edit: and as far as I know all north-american clusters go up to 260.

 

S4 N/A



S4 TII

 

Damn I forgot you guys were speaking miles per hour lol.

 

hmm.. im having this same problem , but there was no swaping on my part...

but from o-20 mph, the needle is really shaky, then smoothes out after 20.... my speedo calbe clicks also.... cant figure this one out..
